Two great friends get separated and their families are terminated by the main villain. The two boys grow up and fight crime individually. One of them, Shiva/Tiger (Amitabh Bachan), is good natured and socially amiable and has a mother. Eventually, he falls in love with the heroine (Rekha) and marries her. Shiva gets blamed for the murder of an innocent farmer (Asrani). On his mother's and wife's behest, Shiva leaves the village and tries to lead a honest and nonviolent life in a faraway village. The other hero Shera/Aslam (Vinod Khanna) too fights crime and criminals but is taciturn and a loner. He gets entrusted with the task of avenging Asrani's death. He tracks Shiva and eventually they both realize that they are long lost friends. Shera also learns that Shiva is innocent. Both of them team up and beat up all the villains.
