Visaranai is a 2015 experimental Indian Tamil-language thriller film written and directed by Vetrimaaran. The film was adapted from novel titled Lock up, written by M. Chandra Kumar, an auto rickshaw driver in Coimbatore. The film premiered on 10 September 2015 at the "Orrizonti" section of the 72nd Venice Film Festival, where it won the "Amnesty International Italia Award". 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.
