A card shark and his unwillingly-enlisted friends need to make a lot of cash quick after losing a sketchy poker match. To do this they decide to pull a heist on a small-time gang who happen to be operating out of the flat next door. Eddy persuades his three pals to pool money for a vital poker game against a powerful local mobster, Hatchet Harry. Eddy loses, after which Harry gives him a week to pay back 500,000 pounds.
