 Based on A.J.Cronin s  Beyond This Place , this movie narrates the story of an untiring crusade for justice. A young man, learning about his father s wrongful implication in a fifteen-year-old murder, vows to bring the true criminals to justice and release his innocent father from  kaala paani  (life imprisonment), for which he enlists the help of a press reporter, a retired police inspector and an unwitting prostitute who happens to possess some key evidence.
