Hoping to improve his skills, pesky Chan-Wing (Sammo Hung) tries his best to persuade kung-fu master Leung Chun-Yau (Leung Ka-Yan) to train him. But Leung -- who's busy evading the crosshairs of his envious stepbrother, Jo-Wing (Chang Yi) -- refuses to tutor the nagging Chan. Leung changes his mind, however, when he needs help to exact a ruthless revenge after his wife's suicide escalates the longstanding family feud.
