Visaaranai (2015)

Four 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 consequences that await 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.
