When a Russian mobster sets up a real estate scam that generates millions of pounds, various members of London's criminal underworld pursue their share of the fortune. Various shady characters, including Mr One-Two, Stella the accountant, and Johnny Quid, a druggie rock-star, try to claim their slice.

Hotshot gambler Jake Green is long on bravado and seriously short of common sense. Rarely is he allowed in any casino because he's a bona fide winner and, in fact, has taken so much money over the years that he's the sole client of his accountant elder brother, Billy. Invited to a private game, Jake is in fear of losing his life.
