Sammo Hung directs and stars in this classic of the genre, featuring some of the best fighting sequences ever recorded on celluloid. One day, while working late on the job, bank teller Chan Hua (Casanova Wong) discovers that his villainous boss, Mo (Fung Hark-on), is plotting to kill the town's chief and take power for himself. When he makes the mistake of telling his associate about the plot, Hua ends up beaten within an inch of his life. Soon after Hua takes refugee at this buddy Fei Chun's (Hung) house, Mo's henchmen murders Chun's mother -- hoping to force Hua out into the open. Instead, Chun enlists the support of humorless kung-fu master Liang Tsan (Leung Kar-yan), who specializes in the Wing Chun form, to teach the two to defend themselves. After enduring weeks of grueling training sessions, the two are ready to face down the baddies, including a new ace fighter who has mastered an exotic fighting form.
