The title 'Layer Cake' refers to the layers or levels the dealer has to go through as he painstakingly plots his own escape. What is revealed is a modern underworld where the rules have changed. There are no 'codes' or 'families' and respect lasts as long as a line. Not knowing who he can trust, he has to use all his 'savvy', 'telling' and skills which make him one of the best, to escape his own. The ultimate last job, a love interest called Tammy and an international drugs ring, threaten to draw him back into the 'cake mix'. But, time is running out and the penalty will endure a lifetime..
In the heart of gangland, two novice unlicensed boxing promoters, Turkish (Jason Statham) and Tommy (Stephen Graham) get roped into organising a bare-knuckled fight with local kingpin villain and fellow boxing promoter Brick Top (Alan Ford). But it all goes wrong when Brick Top's fighter, who is rigged to win, is suddenly knocked out by the boys' wildcard Irish gypsy boxer, One Punch Mickey O'Neil (Brad Pitt). Unfortunately things go from bad to worse as Mickey starts playing by his own rules and the duo find they are heading for a whole lot of trouble.
