Cheung is nine years of age and already a tough little businessman making deliveries for his father's restaurant. As he expertly urinates in the tea he is about to drop off to a thirsty customer, he explains to his accomplice how to get revenge on bad tippers.

Fan is a little girl in a family of poor mainlanders who live in Hong Kong illegally. It is her friendship with Cheung - who navigates their bustling, back-alley neighbourhood, wise beyond his years - that forms the basis for the film. Fruit Chan makes stupendous use of a largely non-professional cast, and even leaves a couple of flubbed lines (alright, it's a dacking) in the film for touching authenticity.

"Chan's films capture the casual brutality of street life for the city's underclass in a manner that can be both highly stylized and rigorously minimalist. With a ruthless sense of economy, Chan's film beautifully depicts the emotional tumult experienced by these two children in a society that thrives on conflict and chaos." - Eye Weekly
