The Owl vs Bombo

Sammo and George Lam, who have been partners in crime, successfully con a powerful triad leader out of a large sum of money and then decide to retire from their criminal activities. Three years later, they each receive letters from Stanley Fung, a former police officer, who claims to have evidence of their past crimes. Fung demands that they follow his instructions precisely, threatening to report them to the authorities if they do not comply. His goal is to use their cooperation to gather information against the same triad leader whom Sammo and George had previously scammed.
