A confusing little period film in which 5 brothers and a sister all seem to have considerable kung fu skills and live on a secluded island. The younger brother for reasons unexplained keeps going to the mainland to challenge the constable to a fight. The constable is a good guy though and at some point during the film the brothers and sister and constable all team up to battle the real evil doer.
