After being hit by a vehicle while being chased during the events of Kahaani, Bob Biswas has woken up from a coma after eight years and does not remember anything even his wife Mary Biswas and children Mini Biswas & Benny Biswas. Two officers from Kolkata Police, Jishu Narang and Kharaj Sahu are keeping an eye on Bob Biswas because unknown to Bob and his family, Bob is actually an assassin. 

After recruiting Bob to be an exclusive assassin to work for them, they give Bob a flip phone on which photos of Bob's targets will be shared. Meanwhile, Mini is addicted to a drug called Blue that is distributed by Bubai Da and his boss Ustaad. After Jishu Narang and Kharaj Sahu send Bob's first target photo, Bob visits a homoeopathy pharmacist Kali Da and receives a pistol disguised as Nux Vomica. Bob then kills his first target Bubai and two of his men. He then leaves for home and meets Mini on his way, who bought Blue from Bubai, a fact unknown to Bob. Bob's second target is Ustaad's investor Rahul who is an undercover police officer investigating Ustaad's illegal activities. Police officer Indira Verma starts investigating the murders of Bubai and Rahul.

After inquiring about Bob, Indira suspects the former and starts keeping an eye on him. On other hand, Ustaad has his henchman Dhonu investigate the murders. Dhonu is close to the Biswas family and is on friendly terms with Bob who visits his noodle stand frequently. While visiting Mary's first husband and Mini's father David's grave, Bob remembers that he has hidden a diary containing names of targets killed, who gave the target and money transactions. With that diary, he finds an unknown key. Bob's third target is Indira's boss but Bob does not kill her after meeting Indira who tells Bob that her boss is instrumental in fighting the drug mafia. Jishu Narang and Kharaj Sahu pay a visit to Bob and enquires as to why he did not kill his third target, to that Bob tells he will not continue on the path and if they force him, he will go to Indira Verma with the diary. Jishu Narang and Kharaj Sahu go to Boss who is a deputy of Indira's boss. Bob visits Kali Da to return Nux Vormica and enquire about the key to this Kali then takes Bob to the trunk room deeper inside his shop and points out Bob his trunk. Inside Bob finds a carrier bag full of cash and becomes happy that now Bob and his family can leave happily in Kalimpong.

Bob pays his dues to Kali Da and returns home. It is revealed that Boss, Jishu and Kharaj are associated with Ustaad. Boss provides Ustaad with a polaroid picture of Bob who has been killing associates of Ustaad. Ustaad contracts Dhonu to kill Bob but Dhonu immediately rejects and is instantly killed by one of the Ustaad's henchmen. Two of Ustaad's henchmen visit Bob in his home at night and torture him, breaking his right hand and killing Mary and Benny in the fighting process. Bob manages to kill both men. Bob is then arrested by Indira but is released as ordered by Indira's boss. Bob visits Jishu and Kharaj and kills Kharaj when enquiring about Ustaad. Jishu takes Bob to Ustaad where Bob kills several of Ustaad's henchmen. Ustaad also known as Doctor Uncle then presents Mini who is now addicted to Blue. Ustaad tells her to kill Bob in exchange for a stash of Blue so she can pass in exams and become a doctor. In the process, Ustaad agrees to have ordered the murder of Mary and Benny and after a struggling fight Bob finally kills Ustaad. Six months later, Bob and Mini visit Mary & Benny's graves and do not talk much as Mini is still angry and unforgiving towards Bob for what happened. After Mini leaves, Bob receives a photo of his new target on his phone, which he happily accepts.^[5]

Additionally, Vidya Balan appears as Vidya Bagchi from Kahaani in a photographic cameo.

In fact, I was all ready to dislike Abhishek Bachchan for playing a character that, in all fairness, belonged to a Bengali actor".^[15] Taran Adarsh of Bollywood Hungama rated the film 3/5 and wrote "BOB BISWAS boasts is an interesting thriller with a fine script, impeccable direction, and good performances".^[16] Devesh Sharma of Filmfare rated the film 3/5 and wrote "It's a layered portrayal by Abhishek and can be counted as one of his best performances so far".^[17]

The expectations remain largely unfulfilled".^[18] Shubhra Gupta of The Indian Express gave the film 2.5/5 and wrote "Every time Abhishek Bachchan gets a killing flare in his eyes, he makes us look. But parts of the plot are predictable and flat".^[19] Anuj Kumar of The Hindu wrote "Despite his earnestness to play a challenging part, two hours is a short time to accept Abhishek Bachchan as Bob Biswas and erase Saswata Chatterjee from memory in this spin-off of ‘Kahaani’.^[20]
