Chai Foon-Cheung (Au Yeung Chun Wah) has not won a single game since his defeat in the World Poker Championship twenty years ago. It is the bad luck he has had all these years that has earned him a job in the casino. And ironically, the man who hires him is one of his then competitors Kiu Ching-Cho (Miu Kiu Wai).
Cheung gets reunited with his long-lost brother Chai Foon-Lok (Wong Chung Chak) through a compulsive gambler named Li Ching-Wan (Hsuan Jessica Hester). Lok has grown to be a reclusive adolescent with an extraordinary gift for gambling. Cho recognizes Loks talent and offers to teach him different gambling skills. On the surface, Cho is a great mentor and friend who looks out for Lok and Cheung in every way, but in reality he has been trying to create discord between the brothers. As a matter of fact, it was Cho who set Cheung up and caused his downfall. Cho keeps fanning the flames of conflict between Cheung and Lok, turning them into bitter rivals on the gambling front
