Advocate Jayant (Rajesh Khanna) a criminal lawyer believes that a lawyers duty is to do service to his client alone and to bail him out of his trouble even if his client is in reality a criminal. His close friend Amit is an honest police inspector who brings many of the goons that are part of gang of smugglers led by Mulchand Malhotra but they are let off by the court when he uses his skills and knowledge about the loopholes in law. Jayant helps Mulchand in setting his workmen free from jail. Amit Gupta asks Jayant to be more responsible when he defends criminals, who are repeat offenders. Later Amit is killed and this motivates Amits brother Vijay to join the police force.

Meanwhile Priya (Jayants sister) falls in love with Vijay and both decide to marry. But one day while going on a picnic Anu (Jayants wife) and Priya get into trouble as their car tire gets punctured on a road near a jungle. There a drunkard who happens to be Mulchands son rapes Anu and injures Priya. On being humiliated Anu commits suicide. Jayant also gets a clue that the death of his friend Amit was not accidental but was a deliberate attempt by some goons and that the rapist is a person known to Mulchand and his gang members.

Jayant tries enlisting the help of his clients Mulchand and Meerchandani in finding the real culprits but realises that they are not responsive. Jayant vows to find the assailants, but before he can attempt anything his daughter, Nandita, is kidnapped. The kidnappers want Jayant to represent Mulchands son in a criminal case, and get him acquitted. Mulchand says his daughter is with them and would be left once his son is let off in a court of law. Jayant gets his client out on bail.

Jayant does not know that his client is the one who had raped his wife and sister, and when Jayant does find out there is noting he can do since his daughter still under the control of her kidnappers. The rest of the story is how he single handedly brings all of them to justice.
