The "Venoms" were no more. After five years and more than a dozen films together, the only one of the original five who proved so successful for the director was the muscleman Lo Meng. But with just that one "venom" and his incredibly agile new star Cheng Tien-chi, he made this spectacular, internationally popular, favorite. Evil ninjas (who attack with, and from, fire, sun, wood, water, and the ground) brutally slaughter a noble Chinese kung-fu school's students. The one survivor finds a teacher and four students who are ninjitsu experts. The five graduates take revenge. With this strong structure and exceptional kung-fu choreography (from the star and co-star Chu Ke), Chang Cheh produced platinum. This film was one of the director's best of his superheroic, grand guignol period. By any name, it could be called, almost literally, "bloody good" entertainment!
