The film opens with a slow scan of photos of crowds of Vietnamese refugees in a HK camp, then cuts to a TV reporter introducing the problem of organized crime among them. Then, under interrogation in prison, Wai Yuen tells the story in flashback. Wai and her boyfriend Tian San assisted corrupt cop Mak to organize a group of Vietnamese refugees into a gang of killers. Each member of the gang, including the very talkative and clownish Fan Wan Tin, was hand-picked for their criminal records. They are strictly warned to stay in the dormitory until they receive orders. One plays a harmonica, and the soundtrack endlessly repeats a refrain, which I think is meant to be the gang's signature tune. Under instruction, they burn down a gym, pick a gang fight with machetes outside a karaoke, cleverly knock off a police informant, then they are given one last mission. In between, they spend lots of time discussing their immigrant dreams, because the encouragement for each of them is to be smuggled to the US.
