Kang-Yi is a teenage girl who lives in an apartment building in the port city of Keelung. Most of her family, and the people in the apartment, are blind, and she helps them out. Ah Ping, who was brought up on the mainland and only speaks Mandarin, comes back to Taiwan after dropping out of military academy. He stays in the same building, and starts to date Kang-Yi. This annoys one of her classmates, who claims she is his girl, and he gets his gang of thugs to bully Ah Ping.
