Shing (Chow) and Betty ( Mo) are two hapless cons who find themselves competing against each other in a game of one-upmanship. However, Betty is in serious debt to a group of loan sharks and when she is seen together with Shing the debt becomes their combined problem. Forced to remain together, the two concoct a plan to break into a rich man's house whilst he is away. Unbeknownst to them though, the loans sharks have also instructed their own man (Wu Ma) to steal antiques from the same house. As if this wasn't farcical enough, when rumours of a rich cousin getting into town filter through, one giant scheme is undertaken by all concerned to fool the man into handing over his hard earned cash. The question is, will any of these idiots actually emerge with any money?
