Opération Dragon
(Enter the dragon)

A martial arts competition is organized by a mysterious man called Han, a former Shaolin monk who now indulges in opium and women trafficking. Lee, a member of the Shaolin temple, is approached by the police to infiltrate and break up the criminal organization. Lee quickly discovers that it was Han’s henchmen who, three years before, tried to kidnap his sister. She preferred to kill herself than be caught.
