An aging kung fu master is attacked and gravely injured by three evil rivals called (appropriately enough) the Three Devils. He is returned to health by a young orphan boy named Gao Jian (Tak Yuan) who wants to be a kung fu master himself, but his skills are pitiful. Eventually the master agrees to teach Gao all his secrets, and he must return the favor and defend his teacher when the Three Devils return. A bit cheesy but the fight scenes make up for it.
