Based upon the human rights violations by the police and the prison authorities in India during the emergency of 1975–1977, the film tells the story of Unnikrishnan, an ex-convict. Recently released from prison, Unnikrishnan relays his life story to fellow passengers on a bus. He tells of his orphan upbringing, career as a forest official, and love for a young woman named Thulasi, whom he promised he'd marry, before he was erroneously arrested for a crime he did not commit.
