Trama

After a cop is found dead, a policeman's investigation starts a chilling search for the truth connected to his fraught past.

The film begins with the murder of ASI Vinod Kumar, the twin brother of DySP Pramod Kumar. There are three suspects in the murder: ASI John, CPO Bineesh, and SCPO Sandeep. All three police officers worked with Vinod in the Vagamon police station and have animosity towards Vinod, due to different incidents. It is revealed through the incidents, narrated by the trio individually, that Vinod was a drunkard and womaniser. Bineesh narrates his incident where he caught Vinod coming out of a lodge room after raping a 17-year-old girl in an inebriated state.

Pramod, is a recovered alcoholic, now sober but long separated from his wife, Sreeja, and daughter. Unable to withstand his drunkard behaviour, Sreeja moved away from him to Mumbai with their newborn daughter. Pramod recalls his and Vinod's childhood. The two brothers grew up in the same household with an abusive and absent father, who also was incidentally a cop. One day, their parents have a violent fight, owing to their father's infidelity. This causes their parents' separation. Pramod stays with their mother, while Vinod is forcibly taken away by their father. This fuels Vinod's resentment towards Pramod and their mother, as he feels betrayed and left alone to face their father's abuse. One day, few people hack their father to death, after he tried to sleep with an underaged girl. Years later, both the twins become policemen, but take different paths. Pramod becomes a respected and honest Deputy Superintendent of Police (DySP), while Vinod becomes a violent and street-smart Assistant Sub-Inspector (ASI).

At present, DySP Satheesh, who has close ties with Vinod, leads the investigation. He also doubts Pramod, as he is aware of the duo's past and hatred towards each other. This is further fuelled by the statement of Vinod's lover, Malini, who recently came into his life and changed him for the better. Hence, Pramod is kept away from the investigation initially, but he requests to take over the case. He quickly proceeds with the investigation, and it turns out that all the three suspects have legitimate alibis. He then finds camera footage from a media personnel recording, in which he sees two children playing cricket with their dog in the nearby field. Upon contacting them, it is revealed that Vinod actually committed suicide by shooting 3 times on his chest and one of them witnessed it while picking up their cricket ball. Puzzled and shocked by the new discovery, Pramod starts to look into the motive for Vinod's suicide, especially since it seemed as though he was very happy after Malini had come into his life. At this point, a few constables receive the footage of the music reality show that Vinod was watching just before he committed suicide. Pramod sees Sreeja in the audience and realises that his now grown-up daughter Shwetha is one of the participants. Pramod suspects the worst and confirms the identify of the minor girl in the lodge raped by Vinod with the reality show footage. Pramod infers that Vinod realised that he raped his own niece and, unable to bear the guilt, committed suicide.

The film ends with Sreeja trying to reconnect with Pramod, after hearing of Vinod's death. However, he strictly instructs her not to tell Shwetha about him or ever show her his face, as she has unknowingly "seen" her father's face on that unfortunate night at the lodge. Pramod, unknowingly, has to now atone for the mistakes and sins of both Vinod and their father.
