The plot begins with the murder of three men who are killed by drug injection at gunpoint. ADGP Mathew Manjooran IPS is retiring after a sabbatical; on his last day at work, he is called by DGP Muhammad Mansoor to investigate the case. Mathew is initially reluctant to help the Police in investigating the case, but realizing the pressure on Mansoor and aware of his medical condition, finally decides to take over the case. He is aided by two officers: ASP Harshitha Chopra and DSP Iqbal. Harshitha says she saw a woman wearing a burqa rushing into a restaurant on the night of the murder; she offered help, but the woman refused and ran away. Seven months ago, Mathew arrested notorious drug lord Felix. D. Vincent, who escapes from custody. Mathew and his wife Neelima accompany their daughter to her new college in Delhi. While en route, he receives a duty call and returns to work, leaving his family to continue their journey on their own. Their car is hit by a lorry, leaving their daughter dead and Neelima comatose.
Meanwhile, three more men are murdered in the same fashion; the victims have a connection with Tharakan's hospital. Mathew deduces the killer to be Shaktivel Palanisamy, a Tamil doctor who works at the hospital. Shaktivel's dark past reveals that his father committed suicide, and witnessing his death causes Shaktivel mental trauma; he sees incidents of malpractice in the hospital, and after graduating, he starts killing the perpetrators, with his girlfriend Dr. Shreya (the woman in the burqa) as an accomplice. Mathew requests that Mansoor relieve him from the case, as the culprit is now revealed, and decides to leave the manhunt to the state police machinery. Harshitha finds out that Felix murdered Mathew's family. She informs Mathew, who already knows this and shows no interest. They receive a video message from Shreya, revealing Felix's location.
Mathew fights Felix and is about to kill him, but draws back, realizing that Shaktivel had targeted Felix, and instead arrests him. Mathew learns that Iqbal helped Felix escape from police custody and asks Iqbal to surrender to the police. He then discovers that Shaktivel's next target is Mansoor, who threatened a patient named Khalid Musthafa in Tharakan's hospital, who later died in an unknown accident. Mathew is sedated, and Shreya takes him to Shaktivel, who plans to kill Mansoor in front of him. Mansoor convinces Mathew that he had threatened Musthafa, fearing a great financial loss, but has no role in his death. Mathew tries to dissuade Shaktivel, who believes that the legal system is corrupt and that what he does is alternative justice. He reveals that Mathew mercy-killed Neelima. They argue and engage in hand-to-hand combat; Mathew defeats Shaktivel, but spares him because he believes that Shaktivel could still become a good doctor after treating his mental illness, were he is taken for mental treatment by police along with Sreya. Mathew is then seen building a school, completing Neelima's last wish.
