Strife for Mastery (1978)

A feudal lord from China sends his son off to kill a criminal who has murdered thirteen of his men and has stolen a large sum of gold. The son abandons his duty (without the will to live an assassin's life anymore) and leaves the Criminal with his life in exchange for his daughter to wed. He runs off with the criminal's daughter, and is then faced with rising conflict and more destruction to his family after he had abandoned his post. He must pull himself together and fight for his life.
