Bon Bon, a resident of Tuen Mun, who's always attempting to implement his latest pyramid scheme. Bon Bon saves daffy local girl Snooker from a potential rapist and decides to implement his latest scheme, "One Dollar Bodyguard": he'll protect women on their evening strolls for one HK dollar. Bon Bon has to attend to his own problem, which is his inability to ride in a moving vehicle, that strands him in Tuen Mun for life. And there's the romantic issue with Snooker to resolve.
