The Righteous Fist(1972)

Once a respected center of martial arts, the Shaolin Institute in Twin Dragon Town now watches helplessly as the ruthless Bear Tiu and his sister, Black Butterfly, seize control of the town through opium smuggling and arms trafficking. With the aging Tiger Yeung unable to stop them, hope arrives in the form of Jaguar Kong, a former Shaolin student and provincial police inspector assigned to bring Bear to justice. After returning home, Jaguar battles Bear's gang, survives betrayal by a trusted friend, and rescues his kidnapped sister. With patience and renewed determination, Jaguar prepares for one final showdown against Bear Tiu in a fight to restore peace to Twin Dragon Town.
