In the present day, a group of rebellious youths rob a bank with the intention of shooting police officers before making their escape. Inspector Chan Kwok-wing and his squad are called to arrest the gang after their hideout is revealed. However, the hideout is rigged with traps, and the entire squad is decimated. Being the sole survivor of the incident, a guilt-ridden Chan takes a year long leave from the police force to binge-drink.
