Takkar revolves around the lives of three characters — Ravi Malhotra, Mohini and Inspector D'Costa. Ravi is a freelance photographer, in love with Mohini, who works hard to make a living so they can be together. Inspector D'Costa is an efficient but corrupt cop who takes advantage of criminals by helping them in return for money and then double crossing them; he pretends to be on the side of the law. No one is considered strong or wise enough to confront D'costa.
One day D'Costa notices Ravi and Mohini on the beach, and he falls for her. He frames Ravi on the day before his marriage to Mohini by falsely implicating him in a drug deal case in a fake raid. Ravi is sentenced to four years of imprisonment. In prison, Ravi decides to study the law so he can fight injustice and is helped by prisoners like Kaku who are in jail because of D'Costa and want to avenge themselves.
