Kung Fu (1972)

Shaolin Monk Kwai Chang Caine is on the run after he killed the Chinese Emperor's nephew after that coward killed his teacher in cold blood with a gun. He flees to America to escape retaliation, and to search for his half-brother in order to settle down in this new land. However, in his travels in the Wild West, he cannot help but continually run into trouble from desperadoes and other ruffians as they oppress the innocent, while bounty hunters pursue the price on his head. Against this, he has his skill of Kung Fu martial arts, which proves to be devastatingly effective in this gun-dominated land.
