Retribution

A rough bunch of men with a herd of cattle came into a frontier farm and shot the man they found in a cabin there. The man's ten year old son witnessed the murder of his father and then left the country to go back into civilization. He came across a shipwrecked Japanese man who raised him and taught him Karate. After the boy became eighteen years of age he went back to the frontier to claim his ranch and see that the scoundrels paid for their crimes. In the process he met a beautiful young lady. They fell in love and were married. In the end he becomes a U.S. Marshall and brings the culprits to justice.
