He is later arrested when Harker spots him acting suspiciously by the canal, looking for something beneath a pile of rubbish. The cases collide when Cafferty is found with a close friend of Lisa's, who reveals Lisa has been hiding out at a friend's house the whole time. Angry and upset, Cryer is shocked when he realises Lisa's father is taking the law into his own hands by planning to kill Morton.

Webb and Riley wait outside a cafe, whilst inside McAllister is conducting a rather clumsy undercover sting on a suspected drug dealer. Cullen is furious when the suspect is released without charge following McAllister's poor handling of the case. Resentful of Singh's success in recruiting local informants, McAllister manages to coax some information from solicitor's clerk Jamie Ross, which eventually leads to a successful arrest when information from Ross blows apart a stabbing suspect's alibi. Pleased with her success, McAllister is determined to convince Ross to work as an informant for her. Meanwhile, Riley meets up with his brother Joe, who seems to be in some trouble with the Nottinghamshire Police.

CID investigate a spate of car thefts, and McAllister's informant Jamie Ross gives her a tip-off about a gang of French car thieves working in the area. Ross is reluctant to name his contact though, who turns out to be Joe, Riley's brother. During a sting operation set up by McAllister, four members of the gang are arrested, but during their bail hearing, are broken out of Canley Magistrates' Court by a trio armed with shotguns. An SO19 raid on Joe's lock-up sees the gang once again arrested before they manage to skip the country, but Riley must work hard to hide his brother's involvement, particularly as Ross informs McAllister that Joe's involvement goes much deeper than Riley thinks.

Worrell and Quinnan attend to a woman threatening to jump off a bridge. She turns out to be Sarah Collins, the wife of DS Terry Collins from Stafford Row CID.

Natasha is desperate as her visa is about to expire, and her sister has disappeared without trace. When her sister is found murdered, Smith realises the men responsible for her death and his assault are linked to a colleague from his old army unit, and goes all-out to discover why someone would want to have him beaten up.

Hoping it will convince Chandler to endorse his transfer to SO19, Smith volunteers with Klein to 'babysit' Clive Allein, the victim of a sexually motivated assault, who is reluctantly testifying against his assailant, Gary Cook, in court the next day. Smith nearly blows it when his angry reaction to teasing from Clive's partner Ian Jones causes Jones to run off, and he is subsequently attacked. Allein subsequently refuses to testify, with Smith tasked with convincing him otherwise.

A petrol bomb attack cuts short a talk by Chandler at a community meeting on the Larkmead Estate, an attempt to improve police relations with the residents. Meanwhile, Ackland is called to the house of local MP Stephen Hadley and his wife Fiona, where their infant child has died of serious injuries. Forensic examination reveals the baby was thrown to the floor, and Fiona claims her husband was responsible. Stephen is arrested, but denies Fiona's claim. A lack of evidence sees him released, but he is subsequently arrested again for attacking his wife when he returns home. After constant finger-pointing and pressure from Chandler to not leak too much to the press, Ackland is left in a difficult position when she finds out who was responsible for the baby's death.

After an ear-bending from Marsha Harris, Chandler is determined to bring to an end the one-boy crime wave on the Larkmead Estate caused by resident hooligan Peter Rogers. Chandler persuades Ackland to talk to Peter's mother, and also tries to get Marsha Harris's daughter Cassie to make a statement to the police against Rogers, but both are too scared of the boy to comply. When Cassie Harris is found half-drowned in a river, and Stamp and Hollis turn up a CCTV tape of Rogers smashing up cars, it seems they may be able to put him away at last, but is all as it seems?

McAllister continues to get useful tip offs from her informant and lover, Jamie Ross, including information regarding a planned armed robbery on a betting shop. Meanwhile, Riley's brother Joe finds himself in the middle of a brewing turf war in Sun Hill, as he attempts to gain ground with his new hot dog vending business, much to Riley's dismay. Unaware that there are some very nasty players on the patch, Joe finds himself making many enemies, and when his lockup is set on fire and several of his vendors attacked, he has no choice but to reach out to his brother for help. Hollis and Hayward join Riley under cover as Joe's hot dog vendors in order to catch those responsible for the attacks.

McAllister, acting on a tip off from Ross, offers Cullen information about a plan to intimidate witnesses in a high-profile court case. However, when Ross refuses to give up any further information, McAllister tapes a privileged conversation between Ross and his client, who admits on-tape to torching the home of the main witness in the court case. When Ross makes an official complaint McAllister, she turns to Riley for help, and threatens to expose his cover-up of his brother's involvement with the French car gang, unless he backs her up and says that he was present at all her meetings with Ross.

Webb poses as a 'rent-boy' in Eddington Park, a well-known gay beat in Sun Hill, as he and Lennox investigate a series of brutal attacks on gay men in the area. A car alarm alerts Webb and Lennox to the car of a local MLA parked in the bushes. When questioned, the MLA claims he was car-jacked and certainly was not 'cruising' in the park. He threatens legal action against the station, and Chandler moves quickly to prevent further damage to Sun Hill's reputation.

Spears takes a particular interest in the case as Chandler has asked her to compile a paper on domestic violence. Meanwhile, Webb is investigating an attack on a lorry driver whose vanload of duty free was stolen following a trip to France. When Neil is later caught on video trying to break into where Lisa is staying, Webb notices crates of French booze in the back of his van. He is convinced Neil will lead them to the gang, and requests that he is bailed. Spears' sympathy for the victim starts to wear thin when she refuses to press charges and begins to harass her at work.

Quinnan and Page attend a call to a suspected burglary, and find the occupier, Mrs Hoyle, who is deaf and blind, tied up in the wardrobe.

When the police leave they argue, and Dave tries to convince Jenny not to leave him. When he shows up late, Boyden stirs the pot by pairing Dave with Stamp, while Page goes out with Hagen. As Dave responds to a call, he sees Jenny on a bus, and when he calls her she says she is going back to Ireland. Distracted by the breakdown of his marriage, Stamp is left assaulted when Dave fails to reach him in time. Dave then goes after the attackers off duty, and investigating officer Webb later gets an anonymous call regarding the whereabouts of the gang, who are found badly beaten.

Quinnan stands and watches as a shopkeeper and a young woman are attacked by a gang of thugs in his local corner shop. When he finally turns up at the station, he identifies the leader of the gang as Robbie Gaitskill.

Smith and Klein both apply for new jobs; Smith submits his application to SO19, and Chandler wants Klein to take the position of partnership officer at the Town Hall. When Kennedy shoots a young boy, and insists that Smith told him to do so, Klein reluctantly confirms what was said. Smith puts his career and transfer at risk when he accuses Klein of grassing him up before savagely assaulting him in the station corridor.

Part Two: Smith, suspended for his assault on Klein, sets out to save his career. Klein is offered the position of partnership officer, but he is shunned by the relief, who think he grassed Smith up to get the job.

With Klein's help, Smith infiltrates the gang of youths intimidating the local residents, and discovers that the real estate firm Mather & Devine is indeed behind the harassment. Cryer makes a breakthrough in the case that could rescue Smith, while he gets closer to uncovering the scam with his off the books undercover op.

Part One: Cryer, approaching his 30th year of service, finds Chandler doubting he is still up to the job. As a test he assigns Cryer the difficult task of resolving a situation where a group of prostitutes are at loggerheads with a local residents group led by Councillor Angela Morris.

The link between the latest robbery and a previous one is revealed to be Jerry Klein, who assessed the security at both premises. When Jerry is found badly beaten, Klein decides he must tell the police about his cousin's possible involvement, which in turn results in Cullen catching the gang on their third operation.

Cryer and Hayward attend an incident at a local school where an angry divorcee, Chris Finnessey, is demanding to see his son. When the boy's teacher warns the police of Finnessey's violent reputation and a possible restraining order against him, he grabs a knife and takes the teacher and Cryer hostage. Faced with an armed suspect and two hostages, Chandler calls in SO19, although the only Trojan unit available is that of the newly qualified Smith and Stanley. When Finnessey and his son leave the school building, Chandler gives authorisation to fire; Smith shoots first, but, to his horror, hits the wrong man.

Ackland visits Cryer in hospital as he recovers from his shooting at the hands of Smith, and is horrified to find that he doesn't know he has already been replaced at Sun Hill. His replacement is Craig Gilmore, who has transferred down from Manchester Police, and who wastes no time in telling the relief that the rumours are true: he is gay. Meanwhile, Lennox investigates the harassment of a local publican by a gang of youths, but when Gilmore organises a 'beat sweep' of the local estates, they find the publican's daughter is involved with the gang and is feeding them information on the police raids.

When Lennox finds a car containing Hayley's blood, forensics drop a major bombshell that blows the inquiry wide open.

It's Boyden's 40th birthday, and to make matters worse, he has to cancel a date to attend an outward pursuit weekend with Hagen and a group of wayward teenagers. CID investigate the serious bashing of an elderly man, and their prime suspect is Jason Wyatt, who had attacked the same man some months previously. Jason is one of the group with Boyden and Hagen, and his aggressive personality causes several arguments and fights over the weekend. Boyden forms a bond with the boy though, and suspects Jason's abusive father had more to do with the attack. Forensics prove him right, but Boyden hears bad news that shatters young Jason.

Stamp joins a dating agency for professional people, telling them he is an antiques dealer, and as he is living in the section house, gives them Page's address.

Webb and Spears investigate a series of robberies and discover a link to Stamp's dating agency. As he tries to keep his involvement undiscovered, CID discover Stamp's date Lisa invites men to stay at her flat and then arranges for their houses to be burgled, so CID set up surveillance outside Page's house.

The relief plan a farewell party for Cryer, but he is reluctant to go, so Conway pays him a visit. The police inquiry clears Smith of charges relating to Cryer's shooting, although his probation period is extended. Meanwhile, Worrell and Clarke attend an apparent non-starter when a series of break-ins occur at the house of a hippy couple, however it is eventually revealed a valuable necklace has been stolen. Elsewhere, Klein and Hayward are called when a strange young woman accuses her neighbour of torturing her elderly mother.

McAllister is surprised to run into her former lover and informant Jamie Ross in a bar, when he returns to Sun Hill after revealing the man who wanted him dead dies of a heart attack. Ross is in a new line of work: organising adventure holidays - but he still has plenty of inside knowledge, and when he and McAllister resume their relationship, he reveals information on the man responsible for a hit-and-run on a drug dealer and a schoolgirl. To McAllister's horror, she realises that Ross has used her, as he is deeply in debt to Brett Sadler, the man who ordered the drug dealer to be killed. Cullen convinces Ross to help them catch Sadler, but he is put in unexpected risk.

Part One: New Area Car driver Des Taviner makes an instant impression on the relief when he starts work on the night shift at Sun Hill, with his no-nonsense attitude and sharp wit impressing the likes of Page and Hayward, however Stamp is wary of his rival’s methods, having briefly worked with Taviner whilst on secondment to the Robbery Squad. Taviner is paired with Worrell, but soon demands she be taken off the role as Area Car operator, saying she is "clueless". Paired with Hollis, Taviner uses his colleague’s experience and knowledge to learn the lay of the land. However, Hollis is later left doubting his new partner when Taviner chats up two girls waiting for the night bus, offering them a lift home. Two drunk girls from a hen party brought in by Stamp and Hayward give Glaze an unexpected break in a series of rapes on the Jasmine Allen estate, but it come too late to stop another attack when residents report a woman screaming on Canley Fields, leading to the entire night shift racing to the scene to track the woman down.

Part Two: McAllister and Glaze are certain they've got their man for the Jasmine Allen rapes; Lenworth Lomanu, a convicted rapist who was seen by Klein and Stamp in the vicinity at the same time Lynn Roberts was attacked. Taviner is not so sure, and he suspects that the young man he and Worrell questioned outside a pharmacy before it was robbed is responsible. As Taviner and Hollis do their own investigation, Lomanu's arrest causes a near riot on the Jasmine Allen, and Gilmore is attacked when he returns two housewives arrested for obstruction back to the estate. Taviner gets his man, Conrad James, but his solicitor gets him off the hook. Clear evidence that Conrad is dealing drugs gives Taviner a second chance and the opportunity to raid his house.

Klein and Taviner arrest two men fighting in the street. Glaze is surprised to see one of the men is his old school friend, Lol Redman. He is even more surprised when Redman is charged with racial assault against the other man, Devon Russell. Redman is bailed, and Glaze arranges to meet him in the pub later. As Glaze waits, Redman is arrested again outside Russell's house, and Russell claims to have a tape of Redman's verbal abuse. McAllister visits Russell's wife whilst he makes a statement, and she admits that she and Redman had an affair, admitting that her husband is a violent and paranoid man. Redman admits he was concerned for the safety of Russell's wife, not realising he is at risk himself.

A ten-year-old boy who calls himself "Billy the Kid" is arrested twice in one day, and when Boyden speaks to him, he reveals he wanted to about his sister, Kate, who is being used as an underage prostitute by her stepfather in a blackmail scam. DI Jane Edmonds from SCG arrives to investigate the scam, an old flame of Boyden. When Billy is hit by a car, he is abducted from St Hugh's hospital by Kate and their stepfather Tom Adams, who is behind the blackmail and whom Kate is besotted with. Edmonds is all for arresting Adams when they use one of the previous victims in a sting operation, but Boyden risks letting him go so he will lead them to the missing kids.

When Joe asks the wrong people the wrong questions, he and Paul finds themselves on the receiving end of a nasty beating. Meanwhile, Page is outraged by a practical joke played by Taviner, but she and Quinnan get their revenge in a most amusing way.

Part One: Singh goes undercover at a 'car cruise', where he becomes involved with a well-organised car ringing gang led by Kevin North, in order to gather information on a scam involving stolen cars, of which leads are very few and far between. Meanwhile, Webb tries to cultivate an unofficial 15-year-old snout named Tyro Shaw, in the hope that he will grass up his father, Steve Shaw, an old nemesis who has a list of previous convictions. Singh poses as a car thief, and is soon initiated with the gang, even gaining a meeting with North's boss, Jennifer Salter. As Webb gets frustrated by Shaw's dead-end leads, Singh discovers he is working with the gang and pushes him too far about his involvement.

Part Two: Tyro Shaw threatens to blow Singh's cover in the car-ringing gang, but is convinced otherwise by Webb. Meanwhile, Singh seems to have impressed both Kevin North and his boss, Jennifer Salter, who seems quite taken with him.

Singh realises he must gather the evidence he needs to convict the gang in North's office, but as he enters the office he is abducted by North and Salter. Webb discovers Shaw blew Singh's cover and is left needing to convince him to tell them where Singh has been taken.

Cullen leads an unsuccessful drugs raid on a warehouse owned by his old nemesis, Terry Barlow. Cullen is furious with Glaze, whose snout tipped them off about drugs on the premises.

Neither case makes any progress until a neighbour reports that Barlow has been to visit the Carters on several occasions. Determined to get one up on CID, Harker puts the pieces together and comes up with a theory that the Carters are putting their baby up for sale on the Guatemalan black market with the help of a doctor at St Hugh's, and Barlow is the broker. Despite warnings from Glaze, Harker presses on.

Part One: With the Section House closing, Hollis is not only looking for a new place to live, but is also applying for a transfer to SO14, the Royal Protection Unit. As he closes on a sale to buy a flat owned by an elderly friend, Doreen Tyler, she changes her mind at the last minute, so he moves in with Stamp. Hollis's intuition gives CID an important lead on a planned armed robbery, but his uniformed colleagues conspire against him to have Klein organise the Section House closing party instead of him. Upset that his colleagues no longer value his credibility, Hollis decides to skip the party and goes round to visit Doreen, only to find her lying on her living room floor with head injuries.

Part Two: When Doreen Tyler dies of her injuries, Hollis is named as the prime suspect for her murder, leading to a suspension from duty and breakdown of his hopes to transfer to SO14. While CID try to trace the victim's long lost daughter, with little to no information, Stamp and Klein try to find an alibi for Hollis. They interview a witness outside of Doreen's house, who claims that he saw Hollis hanging around the property more than hour before he stated that he arrived. With the evidence mounting, Stamp and Klein's only hope of clearing Hollis' name lies with a tom. Meanwhile, a scam involving Tyler's 'long-lost daughter' comes to light, which the Sun Hill team hope will clear Hollis.

Part One: Chandler takes a personal interest in the case of a shooting at an off-license. When he confides his reasons to a young woman who was threatened by the gunman, he is horrified to find she was a journalist, and the story is published in the Sun Hill Gazette. Feeling unappreciated in the job, Meadows considers other options, and attempts to smooth things over with his long-suffering wife, Laura.

After a minor car accident in the High Street, Carver breathalyses an elderly man, but takes sympathy on him and allows him to leave in a taxi. The man turns out to be Hugh Alexander, a High Court judge with a renowned pro-police stance, and Carver finds himself suspected of showing bias, particularly when the other man involved in the accident threatens legal action against the Met. At the trial of a man accused of murdering a police officer, Worrell feels marginalised as a black officer when she is asked to testify and be a character witness for the dead officer. Conway meets with Gary Fablon, and after discovering that Fablon is addicted to litigation, Conway suspects Fablon caused the crash.

A spate of graffiti taggings in Sun Hill sees the police showing zero tolerance to the perpetrators. Carver is sympathetic towards an alcoholic teacher at Canley Art College when his classroom and students' work are defaced. Boyden asks Hagen to move in with him, but she is reluctant, wanting her own space. To her outrage, Boyden moves her belongings to his house as a surprise. Boyden arranges for the council to paint a wall blank to set a trap for the graffitists, catching quite a few in the process. However, with all them pleading innocence for the art school incident, they are left looking elsewhere.

Clarke, who has been working double shifts all week, goes behind Ackland's back to get some more overtime from Boyden as she is desperately in debt. Taviner promises her some time in the Area Car, much to Hollis's annoyance. Taviner and Clarke interview Warren Debdale, a student who was brutally beaten, but he insists he didn't know the perpetrators. His father suspects the boy's friends are involved, but Glaze discovers the father is being blackmailed by a drug smuggling gang. Assigned to watch Warren in the hospital, Clarke has a coffee with a nurse, and is horrified to find Warren missing when she returns. Clarke's flatmate then threatens to throw her out unless she pays the rent.

Glaze is outraged when Clarke falls asleep on an obbo watching the Borrovitch brothers, who are suspected of running a protection racket. Taviner and Clarke then investigate the theft of stolen diggers on a building site. The main suspect is Mick Abbott, an occasional employee at the site, and when they visit him in the bus where he lives, his wife reacts angrily and attacks Clarke. Desperate to clear her debt, Clarke begins moonlighting in telesales at her flatmate's company. While out at a bar with her new co-workers, she spots the Borrovitch brothers, allowing Glaze to make a connection with the stolen diggers and German arms dealers, and a successful raid sees all the culprits behind bars. However, Clarke's joy at getting a result is shattered when she attends a fatal RTC.

Clarke fails her probationer exams, and goes AWOL instead of returning to the station. A gang of thieves on rollerblades are rampant in Sun Hill, and their mobility makes it very difficult for the police to catch them. Taviner arrests a girl, Jackie Burns, at a skate park, but she insists she was just watching the skaters. As the skate gang gets more violent, animosity between Worrell and Clarke also grows fiercer, and the two come to blows in the corridor. A tearful Clarke admits her debt problem to Taviner. Scrutinising CCTV footage reveals Jackie's involvement with the gang; she phones them when a potential victim withdraws money from an ATM. Clarke discovers her telesales commission has fallen through.

Clarke unsuccessfully applies for a police loan. Taviner buys her a pushbike and suggests she sell her scooter, but she is far from impressed. Meanwhile, Carver and Rickman find a young boy, Gavin Billson, overdosed on drugs, and Glaze and Webb investigate some of the local dealers. When it turns out Gavin overdosed on diamorphine, and after several dead ends, suspicion falls on Dr Stuart Bremner, a doctor at St Hugh's, who is also the boyfriend of Clarke's friend Ruth. A review of the hospital's CCTV footage reveals Ruth herself sneaking into a storeroom, and Clarke is forced to arrest her best friend. When Ruth refuses to grass up her lover, Clarke finds herself in a very difficult position.

Part One - The Dark Side: Hayward breaks down during a talk with primary school pupils, when he gives a powerful speech about the death of his sister to teach them the dangers of drugs. Gilmore is not happy, but the teacher thinks Hayward's sensitivity will help the students get the message, and may also help them trust Hayward enough to report a bully. An old friend of his sister's asks him out, although when he meets her at a gallery opening, Hayward thinks her friends are dealing drugs. Klein and Hayward find the bully, "Red", who has been using two fierce dogs to steal money and mobile phones from school children. They trace the dogs to the flat of drug-addicted prostitute Stacy Dodds, and a search of her flat uncovers a large stash of heroin. CID are drafted in when Red accuses Stacey of sexual abuse.

Part Two - Angel Rooms: Hayward and Klein arrange to get their stories straight over the missing bag of heroin. Stacy insists her pimp forced her to deal drugs and have sex with "Red". Clarke ends up sleeping with "Phil the Pill", and is surprised when he turns up at Sun Hill the next day and announces himself as DC Phil Raven from the Drugs Squad. Raven arrests Benji Pullinger for intent to supply, but inevitably the missing bag is mentioned in the interview. Station gossip starts to point towards Klein, and Hayward confesses to Gilmore what really happened. Whilst out at a nightclub with his new girlfriend, Fiona, Hayward sees Raven selling drugs, and discovers that he and Fiona are former acquaintances.

Part Three - Paint it Black: With Klein's help, Hayward tries to set up a sting to catch Raven in the act, by offering to sell him the missing bag of heroin. They decide to meet in a car park, and Hayward, carrying a bag full of baking soda, is surprised when the tables are turned on him and Raven arrests him for possession.

The Sydney police tell Stanton that Beech has linked up with Vietnamese criminal Frankie Nguyen, with the pair going from partners in crime to romantic partners in the nine months since Beech landed in Sydney. The local force suspect that Beech has flown under the radar thanks to recently suspended local officer Bill Mayle, who puts Beech in touch with a local drugs kingpin. Beech's greed sees him raid Triad leader Joey Tranh, who then holds Nguyen's pregnant sister hostage to get Beech's location. Stanton attempts to derail a drugs raid on Beech so he can be arrested for Boulton's murder instead. As Stanton and her police contact find Beech's hideout, Tranh shows up to murder Beech, but when shots ring out it's Tranh who is found dead.

While Beech's old friend Tommy cashes up his haul, Beech's firm are becoming increasingly frustrated at not receiving their cut of the cash.

As Tommy refuses to deal with Frankie, she lashes out, leading to disastrous consequences.

Part Two: Beech informs Tommy's daughter Stella that her father was murdered, and promises to find his killer. Meanwhile, Frankie panics about being seen by Stanton, who is hot on her tail.

Frankie starts to become more and more agitated at the fact that Beech wants to stick around in London, and Beech gets the shock of his life when Stanton turns up at Tommy's shop. Stanton gets a shock of her own when an anonymous tip leads her to find Beech at a local graveyard, but Beech is determined not to let Stanton get the better of him once again.

Part Three: Beech takes Stanton hostage in his car, but on the way to a secret location, is pulled over by two uniform PCs for his erratic driving. Posing as 'Matthew Boyden' from Sun Hill, Beech once again makes good his escape and takes Stanton to an underground bunker where Frankie urges him to kill her. When he refuses, Frankie decides she'll have to do it herself, or risk being taken in and imprisoned. Beech disapproves of Frankie's methods when she uses forms of torture to gather information from Stanton. Frankie realises that Beech may no longer be on her side, so she goes over the side and offers to help Stanton in any way she can.

Part Four: Beech's trust in Frankie begins to slip, and as he sends her out on a number of errands, he keeps an increasingly twitchy Stanton under lock-and-key. However, Stanton manages to make radio contact with an outsider and he alerts DS Peters and DCI Belmarsh from the Robbery Squad, who begin a search for the underground bunker where she is being held. In an effort to escape, Stanton breaks the lock and shatters any chances of Beech letting her go.

However, Beech hatches a plan that puts everyone in the vicinity at risk, including himself.

As Rachel holds Beech up in an apartment supposedly owned by her married lover, Stanton recovers in hospital. When Beech discovers that Frankie is trying to broker the deal without him, he goes in search of his former partner, only to be cornered by Giorgio, who turns up at the handover and demands his share of the money. As the tensions rise, bullets fly, leaving several members of the gang dead.

Part Six: Following his murder of Giorgio and the shooting of Frankie, a devastated and wounded Beech leaves the bodies behind and flees with the takings from the robbery. Beech escapes once more, unaware that a fully recovered Stanton is hot on his tail. Stanton trails Rachel and discovers that she is sleeping with Mal Lockye, a bent police officer whose deposit box was raided by Beech during the robbery, and Rachel has been setting up Beech in order to get Lockye's money back. As a wounded Beech makes good his escape, his plan falls to pieces when he realises that not only has Rachel lured him to a false getaway, but that she was the one who set Stanton onto him in the graveyard. Stanton takes control and Beech begs her to kill him to get justice for John, but she has a different idea of what justice is.

Meanwhile, Cullen is trying to prove his worth to the NCS, and uses the news of Leroy's return to try to get his feet under the table. When Leroy is implicated in an investigation regarding an undercover police officer, Rickman wonders if she has given too much information away, and finds herself testing her own loyalties.

A search of the furniture by Customs reveals no drugs as suspected, so Leroy is released. As he angrily heads off to the airport, leaving behind a distraught Rickman, his fingerprints are found on a gun used to murder an undercover NCS officer, DS Hanbury.

Part Three - In Another Life: Harker tells Cullen that he knows Leroy didn't kill DS Hanbury, but CID use the charge as leverage to convince Leroy to help them catch Resenbrink.

As Boyden lets her go, Hagen rings to alert him about CID's plans.

Boyden meets up with an old acquaintance, ex-fighter Billy Briggs, who tells him about an illegal fight being organised by Kieron O'Shea, and offers his services as an informant.

Later, Spears decides to keep an eye on Cork, and follows him to a pub where he meets up with an old mate, DI Freddie Collins.

After trying to dig up information on Cork, Eddie disappears without trace.

Following a lead from Cork about a rapist he pursued years earlier, Rawton consults an ignorant DI Collins, but Cork demands he "play nice". Meanwhile, Spears is fruitlessly searching for her missing friend Eddie. She fears for his safety when Cork hands in his phone, claiming to have found it.

Ferdinand proves evasive, despite evidence that he has been in Spears's flat the night before. A search of his house uncovers a large amount of money and a passport, but Rawton realises it is a decoy, and Spears goes in search of the real running-away kit.
