Hua Heng is a poverty-stricken aspiring painter whose day job involves painting the ads that go up on the sides of buildings. He and his buddies hang out in a makeshift gym set up in an abandoned building where they train and practice kung fu. His girlfriend is Gao Xin, a bar maid who is in debt to loan sharks. Into their lives comes Jiaji, who happens upon Hua Heng in a street fight with local thugs who'd made fun of the painting he's carrying and decides to help him out.
