Grandmaster^[1] is a 2012 Indian Malayalam-language action thriller film^[2][3] written and directed by B. Unnikrishnan and produced by Ronnie Screwvala and Siddharth Roy Kapur under the production company UTV Motion Pictures. The film stars Mohanlal as IG Chandrasekhar, a senior IPS officer who begins investigating a series of murders after receiving an anonymous note. The supporting characters are played by Priyamani, Narain, Anoop Menon, Babu Antony, Jagathy Sreekumar, and Arjun Nandhakumar.

Grandmaster was the debut Malayalam production of UTV Motion Pictures. The film was released on 3 May 2012 to widely positive reviews from critics and was a success at the box office.^[4][5] Grandmaster was released in the online video streaming service Netflix in the United States and Canada, making it the first ever Malayalam film to be released on Netflix. It was also the first Malayalam film to be released with English subtitles outside Kerala. The movie is based on the book The A.B.C Murders by Agatha Christie^[6] which was already adapted by Unnikrishnan for the script of a TV series named Black and White.

IG Chandrasekhar, is the head of the newly created Metro Crime Stopper Cell in Kochi. Chandrasekhar arrests Jerome, a psychologically deviant man, and rescues three girls he had kidnapped, but his ex-wife Deepthi, who is a lawyer, manages to get Jerome sent to treatment in a psychiatric facility run by her friend Dr. Jacob, rather than a prison sentence. It turns out that the three girls had been insulting and harassing Jerome, which had led to his actions of kidnapping them in the first place.

Chandrasekhar gets a congratulatory note from an anonymous man who calls himself as "Z," who challenges Chandrasekhar to figure out how he is going to bump off one target after the other. Chandrasekhar is forced to investigate a string of 3 murders: Alice, a coffee shop owner, Beena Thomson, a famous singer and Chandrika Narayanan, a leading businesswoman. These murders follow a mysterious alphabetical pattern and each victim also has a cross slit on their forehead. Around the same time, Chandrasekhar's daughter Dakshayani is preparing for a play under the lead of famous actor Mark Roshan.

Chandrasekhar divorced Deepthi ten years earlier as he discovered that Deepthi was using information from him for a professional gain. Deepthi confesses to Chandrasekhar that the three recently murdered women were all involved in the murder of a rich NRI named Paul Mathew and made it a suicide. Chandrasekhar realizes that Deepthi is the next target and comes with her to their daughter's play, where they meet a religious fanatic named Victor Rosetti who had been present in all three crime scenes, disguised as a salesman and has been followed Deepthi. The recurring theme of chess is obvious in the game between Chandrasekhar and the Z.

Chandrashekhar understands that there is a mastermind behind Victor Rosetti and decides to play a 'queen's gambit' in his own words. Chandrasekhar finally manages to corner Victor on the rooftop of a theater, and Victor commits suicide by falling off the rooftop to the pavement. Then, Chandrasekhar questions Dr. Jacob and says that he has evidence that he is the killer of the three women and takes him to custody. Dakshayani goes missing and Deepthi goes back to the school to find her. The real serial killer arrives and tries to strangle Deepthi with a red scarf. Fortunately, Chandrasekhar stops him and then finally corners him on the stage. The killer turns out to be none other than Mark himself, who is then revealed by Chandrasekhar to be Paul's younger brother Roshan Mathew. He reveals that he framed Dr. Jacob to mislead Mark and shifted Dakshayani with his colleague Rasheed's help to bring Deepthi alone to Mark.

Mark confesses that he has held a grudge against the women for his brother's death, which Chandrasekhar had already known. Then, Mark also confessed that, disguised as a priest named Father Alexander, he manipulated Victor, who was a schizophrenic patient, into believing that he had committed the murders himself. He had planned for Victor to commit the final murder on Deepthi during the play, but attempted to use the scenery of the fight between Chandrasekhar and Victor to complete his plan. In a last-minute attempt to avenge Paul's death, Mark tries to jump from the stage to murder Deepthi with a dagger, but Chandrasekhar kills him with his gun and saves Deepthi.

The film then ends with Chandrasekhar and Deepthi, along with Dakshayani, finally together again in their house.
