Yeh To Kamaal Ho Gaya (1982)

This fast-paced crime drama incisively probes into the flaws of the current system of law in India, and the devastation caused in the lives of ordinary citizens, due to rampant corruption. When heartless and corrupt lawyer, Rashik Bihari Saxena, frames an innocent child, Mahesh Chander, the son of a convicted thief, for murder, the young boy is sent to juvenile jail for several years. His father, Shankar, swears vengeance against Advocate Saxena, abducts one of his identical-twin sons and names him Ratan. He and his wife, Shanta, nurture him and let him grow with them. Shankar teaches him all the tricks that would make him a master cat burglar. Years later, Ratan has grown up to be a master cat burglar while his lookalike brother, Ajay Saxena, is studying in London. Ajay returns home with a Caucasian wife, Kathryn, who is not welcomed by Advocate Saxena, as a result Ajay too leaves the house. Then a woman named Ruby Gupta is killed, and the evidence links this crime to Saxena. The police arrest him, and a trial is conducted. In the meantime, Shankar asks Ratan to take Ajay's place in the Saxena household, which Ratan does so. As a result, Ajay is framed for a robbery, is arrested and held in jail. With both father and son awaiting respective trials, it looks like Shankar is going to have his vengeance after all.
