A young and unworldly kung fu student is now the student of an evil teacher, the villainous Manchu Lord Tsoi. The young impressionable man soon learns that his choice has made him a villain to his own family and people.

The violent tale of an undercover agent's mission to topple a Chinese opium ring that is headed by a ruthless kingpin known only as "The Tongfather."

Watch WANG YU as a one-armed savior battling the local goons in this martial arts classic. He has some rather amazing moves up his sleeve.

The plot is a standard revenge tale told in a concise manner that involves a boy witnessing his parents' murder at the hands of corrupt officials and growing up to achieve vengeance. The boy goes to Shaolin Temple to learn kung fu in a superb training sequence that ranks with some of the better-known Shaolin Temple scenes in kung fu cinema. By the time the boy has completed his training, he has grown up to be Carter Wong and soon sets out on his mission. He meets Polly Shang Kwan along the way and, after some initial antagonism, the two become allies and confront the villains. The bad guys employ a particularly clever maneuver involving dozens of imperial guardsmen performing a variety of formations on cue (including standing on each other's shoulders, three men high) as Sammo Hung bangs out different drumbeats. Sammo and Carter engage in a particularly exciting bout against the backdrop of a mountainous landscape midway through the film.

Rare was the film in 1973 that incorporated the star's name in the title. One of the few such films was Screaming Ninja, aka Wang Yu, King of Boxing. The story is set in China in the early 1900x. Essentially playing an extension of himself, action-star Wang-Yu spends much of the time defending himself against evil martial-arts masters. He also tries to make sense of a tragic incident in his past.
