Beneath his aristocratic facade, "Lord Freddy Doyle" is revealed to be Brendan Reilly, a disgraced Irish solicitor who embezzled over £900,000 from an elderly client's trust fund in the UK before squandering it all in Macau.
The central supernatural twist reveals that Doyle's guide and benefactor, Dao Ming, is already dead, having drowned during a previous Hungry Ghost month. The sudden, legendary winning streak Doyle experiences at the baccarat tables is recognized by local dealers as a gambler playing with "a ghost attached."
In the climax, Doyle utilizes Dao Ming's funds to win a monumental fortune. Rather than fleeing Cynthia Blithe or repaying his legal debts, Doyle recognizes the futility of his material obsession. He brings the bundles of cash to a Ghost Festival altar fire and incinerates them as an offering to Dao Ming and the wandering dead, successfully breaking his addiction and redeeming his soul.
