Go Do Gaai Bei plot
Kwan, a former expert in blowing up old buildings, is in prison for murder. However, his influence on the outside world is still so great that Inspector Pao rightly fears an escape. Because the horse races in Hong Kong involve very large amounts of money, Kwan is ordered by the Taiwanese Triad (the Chinese mafia) to rob the heavily guarded vault of the gambling proceeds. The multi-million dollar drive makes Kwan an even more cunning and tougher adversary than he already was. After his spectacular escape from prison, it becomes a matter for Pao to get the ruthless villain back under lock and key.
