Daag: The Fire.

Karan is a former soldier. One day when Karan finds out that his father committed suicide in prison after he is falsely charged with a crime, he suspects Ravi Verma, a city attorney who has a wife and a kid. When Karan spots Ravi on the street with his wife Kajal, he abruptly shoots Ravi and Kajal; however, Ravi survives the murder and Kajal ends up dead. After Ravi's release from the hospital, he does not realize that he has a new and different wife who looks exactly like Kajal, later on he does. While Ravi's life continues, Karan's revenge also continues against Ravi. Ravi claims that it wasn't his idea to set Karan's father up, it may be Ravi's father-in-law and his colleagues who may be responsible.
