For reasons which only the audience knows, A Dai has left his retarded mother behind in the village he was born in and has migrated to the city of Taipei. There, he proves his complete absence of fear and his brutality in order to get a job with the city's gangster boss. In front of his would-be employers, the burly youth throws a pedestrian through a shop window, stabs him for good measure, and then drops some coins in a machine for a soda, which he calmly drinks. The bad guys are impressed and quickly give him the job of guarding Lin, the boss. Occasionally, when the boss is out of town, he simply protects the ganglord's wife and small daughter. Lin's wife is a former bar-girl and finds A Dai's masculinity quite arousing. ~ Clarke Fountain, All Movie Guide
