The incredible career of perhaps the greatest boxer of all time - Muhammad Ali - is dramatised in this exciting film staring Ali himself. Fresh from his gold medal victory at the Olympic Games, 18 year - old Cassius Clay is ready to seek the heavyweight championship. Under the masterful guidance of trainer Angelo Dundee, Clay snatches the title form Sonny Liston. Soon afterward, Clay converts to the Islam religion and changes his name to Muhammad Ali. When he is suddenly classified 1A by the Draft Board that earlier rejected him, Ali refuses the draft on religious grounds. His hard one title is taken from him. Winning a three-and-a-half-year long court battle, Ali returns to the ring for what may have been some of his greatest fights of all time.
