 Lee, a member of the Shaolin Temple is asked by a man to go to a tournament that is being on an island that belongs to man named Han, who is a former Shaolin monk, who went renegade. The man tells Lee that they believe that Han is involved in Opium trade and white slavery. He wants Lee to go there and try and get him the evidence they need so that go there and arrest Han. Lee agrees but is then also told that Han s men tried to abduct his sister three years ago and rather than submit she committed suicide. Lee now has a personal stake. Also going to the tournament is a man named Roper who is in a financial bind with some men, who collect one way or another, and Roper is hoping to find a way out of the hole he is in.
