The Owl vs. Bombo

In Owl vs. Bombo, Sammo (Bumbo) and George Lam (Owl) are partners in crime and they scam some triad big shot out of a load of money and decide to retire. Three years later they both receive letters from Stanley Fung, in which he informs them that he has proof of all their criminal activity and unless they do exactly what he says-he will turn it over to the cops.
