Cardsharp Who-the-Hell (Cheung) travels to Shenzhen for his latest sting, fleecing $800,000 from a dimwitted mark (Lam Suet), with the help of his Uncle Lo (Wong). While celebrating their victory in a nightclub, Lo unknowingly hits on the girlfriend of local triad boss Tough Ho (Lung Fong...you just knew he'd be in here somewhere, didn't you?) and only Who's impeccable skills save them from being chopped. Back in HK, the gambler falls in love with blind model Candy (Hsu Chi), whose father, Chicken (Hui Shiu-hung), has been squandering money that was meant to cure her eyes.

Tough pays a surprise visit and demands that Who and Lo join up with him for a series of swindles. All three profit handsomely from this arrangement but Candy, a practicing Christian, disapproves of Who's vices and her dad turns out be his next patsy. Chicken has stolen all of Candy's money and already lost $2 million of it, prompting Who to let him win it all back. However, Tough removes Who from the game and replaces him with Who's scheming protégé, Chun. Chicken's fortunes quickly go south and during the inevitable fight afterwards, Chun bashes his former master in the head, leaving him sightless. Lo sells all of his assets and Candy is still able to have her operation but the humiliated Who does his best to avoid her. He is eventually able to overcome this shame and seeks revenge, providing the set-up for the requisite high stakes finale.
