Richard Cheung Kuen

A career criminal, Ah Sang, engineers a bank robbery to be carried out by a gang of recruited hoodlums led by himself. It takes only three minutes to complete the robbery of seven million dollars. A special police unit is then formed to investigate the case, and the chief inspector suspects Sang, and begins keeping him under surveillance. In order to stay undetected, each member is specifically ordered to not spend their share of the one million HKD from the heist for six months.
