A father finds out that his teenager daughter is possessed, and the only way he can save her is by doing the ghost's bidding, which will mean an encounter with his long-separated twin - who happens to be a psycho killer.

A group of immigrants (Pandi, Murugan, Afsal and Kumar) are detained by the local state police, tortured and forced to admit to a crime they have no knowledge of. When all hope seems to be lost, a policeman from their hometown speaks on their behalf at the court hearing, setting them free. The policeman asks for a return favor and the boys oblige, oblivious to the ill fate that awaits them. As they unwittingly bear witness to a political treason, the system seeks to silence them, at any cost. But Pandi is determined to be heard.
