[6][7] The film follows an investigation in which a woman and her mother are suspected of murder after a disfigured corpse is found, while their neighbour claims to have committed it instead, much to the surprise of cops.

[8] It is an uncredited remake of the 2012 South Korean thriller film Perfect Number, which was based on the 2005 Japanese mystery novel The Devotion of Suspect X by Keigo Higashino.

The next day, the body is found by the locals, and a crime branch DCP Karthikeyan (Arjun) is assigned to the case.

He starts an investigation on complaints of missing guests at hotels within Chennai, and from the information extracted from the tag, he discovers that the murdered man is Vamsi, the younger brother of an influential minister in Andhra Pradesh.

The tale takes its turn in the final minutes, and all of the police officers but Karthikeyan believe that the case can be closed as the murderer Prabhakaran has surrendered.

Karthikeyan can not believe that Prabhakaran, a police officer who is known for solving murder cases, could make amateur mistakes when disposing off Vamsi's body.
