Aakhri Muqabala (1977)

Hero #1 fights a cadre of bad guys with his superior kung fu skills. Eventually, however, the bad guys get the best of Hero #1, and break off one of his legs. Fortunately, Hero #2 steps in to save the day. Hero #2 is given a photograph of each of the bad guys who crippled Hero #1. He tracks each one of them down, ripping up each bad guy's photo once he locates him. Hero #2 engages in a kung fu fight with each bad guy, defeats each bad guy, and takes his revenge by breaking the bad guy's leg (or worse) at the end of each fight.
