Vijay (Amitabh Bachchan) and Ravi (Shatrughan Sinha) are best friends who do not question each other about their careers. Vijay is a police officer and Ravi is a lawyer. While Vijay catches criminals, Ravi bails those criminals out and is employed by Daaga (Prem Chopra). One day both Vijay and Ravi meet Sheetal (Zeenat Aman) at different places and times, and both fall in love with her. While Vijay's love is more vocal and is reciprocated by Sheetal, Ravi has one-sided crush on Sheetal.

Ravi admits his love for Sheetal to Vijay who is devastated but decides to sacrifice his love for Ravi's sake. However, there is a misunderstanding when Daaga decides to stir up Vijay and Ravi's friendship by showing Ravi a photo of Vijay and Sheetal. Vijay and Ravi become rivals for the first time. The rest of the movie looks at the conflict between Vijay and Daaga. After the misunderstanding, Ravi is on Daaga's side but later learns the truth and atones for the his deeds.

The court scene nearing the climax, when Ravi argues on the side of Vijay and saves him from legal punishment is impactful. And so are the action scenes, almost all of which were filmed on Amitabh Bachchan, who gave power packed performance in all of them. It was not without any reason that Amitabh was called the 'Angry Young Man' and biggest action star of the era.

Pran also plays a crucial role in the movie, and so do Helen. This was among those strings of action movies in which Amitabh and Pran were paired together. Almost all of those movies were Super Hits.
