Two members of the Indian Police Service (IPS), Commissioner Sreebala and Assistant Commissioner Xylex Abraham, investigate the disappearance of the actress Uma Sathyamoorthi. Sreebala and Xylex arrest Melvin, who, as it turns out, is a classmate of Uma's. During the interrogation, Melvin reveals that he had murdered his wife Sherin and covered it up as a drug-induced suicide in order to take revenge on her for her infidelity. They find that Uma was kidnapped because the guy she was with was the one who had been having an affair with Sherin. However, Melvin refuses to point out where he dumped their bodies.

Sreebala and Xylex are pulled off the case, though not before seeds of doubt are planted by Melvin. Sreebala begins to uncover clues about her father's accident, which had rendered him mentally challenged.Doubting that Xylex may have played some part in the scheme,Sreebala loses her trust in him. Xylex begins doubting his wife and soon takes it upon himself to murder the guy she hangs out with, echoing Melvin's own crime.

Soon, Melvin agrees to give up the bodies, provided Sreebala and Xylex take him there. They discover that Melvin hadn't actually killed them, and they were just being held hostage. Melvin is sentenced to the asylum, and the case is apparently closed. Xylex finds out that the guy who he had killed, Ronnie, was facilitating the adoption arrangements with Xylex's wife, and they'd been keeping it a surprise for him. His involvement in the murder is only known to Sreebala, who receives a video of the murder.

In a twist, Melvin's wife is found to be innocent of having an affair. She was actually murdered, but not how Melvin had described it. Sreebala and Xylex approach Melvin, who reveals the whole story behind his actions. His daughter had been abused by the school's headmaster and the owner,which led to her death shortly. The school owner, who is revealed to be Ronnie, had used his influence to silence the case and murdered Sherin in the process. The police officer in charge of the investigation was Sreebala's dad, and he was attacked because he had been close to finding out the truth. In pursuit of justice for his family, Melvin had set up the whole kidnapping drama with help from his dad,who,while from behind the scenes, had been manipulating the people around him to achieve what he couldn't on his own. Xylex was targeted because of his wife's friendship with Ronnie, and Sreebala through her dad. It is revealed that Melvin planted doubts in Xylex so he would murder Ronnie and made Sreebala accidentally kill the headmaster as they were driving through the forest,making him innocent of any murders.
