The film concerns Wang’s one-armed martial arts master being stalked by an imperial assassin, the master of two fighters (the Tibetan lamas) who were killed in the previous film. When the One-Armed Boxer is invited to attend a martial arts tournament, his efforts to lie low are unsuccessful, and the assassin soon tracks him down with the help of his three subordinates competing in the tournament: a Thai boxer, a yoga master, and a kobojutsu user. The title refers to the assassin’s weapon, the “flying guillotine“, which resembles a hat with a bladed rim attached to a long chain. Upon enveloping one’s head, the blades cleanly decapitate the victim with a quick pull of the chain. A tagline calls it “The Most gruesome weapon ever concieved”.
