Hsiao Kang is a cab drivers son, driven to study by his parents, who are ambitious for him to go to college. One day, the family cab is vandalized by some kids on motorbikes while Hsiao Kang is watching. One day, he recognizes the culprits, and drops out of his college preparatory after-school cramming sessions to pursue them and get revenge. The vandals are Ah-tzu, with a permanently flooded apartment, and his brother Ah-bing and Ah-bings girlfriend Ah Kuei. They are petty thieves of telephone boxes and computer parts. The seedy side of Taipei which is favored by teen rebels is well-screened in this action drama, and might almost qualify as a fifth character. ~ Clarke Fountain, All Movie Guide
