After three of his fellow officers are blown up by a bomb concealed inside a pizza box, NYC cop Chung (Lui Chi-yin) finds himself out of work and on the streets of Manhattan selling hot dogs. Chung's young son and a schoolmate are kidnapped by some Italian gang members out to blackmail the other child's father, triad drug dealer Chen (Chan Kwan). Chung and Chen are able to affect a rescue and the gangster convinces Chung to join his gang. He agrees, in order to help the DEA take Chen down, and begins receiving orders from a female boss (Alana Adena) who dresses like a Park Avenue hooker. In the meantime, the power-hungry Chen kills his boss and ingratiates himself with Chung's wife (Carrie Ng Kar-lai, the only name performer here), dragging her into his criminal operation.
