Tom is a recreational drug user. He knows a guy, who knows a guy, who knows a guy, who knows a guy... and he comes to wish he didn't.

In an attempt to ease his financial dilemma Tom bites off more than he can chew when he decides to impersonate a dealer whose murder he accidentally witnesses.

But Tom is soon to realise he's not as street savvy as he'd like to believe when a series of blunders, incited by lifelong friend Flaco, a stone-head sure to test the patience of a saint, see the debt quickly mount and a progressively more terrifying succession of heavies come knocking.

Unwittingly Tom is plunged head-first into a world of dealers, deals and death enacted by a mysterious assassin who stalks his every move. Will he make it as a dealer? Will he find his way out? Or will he wind up where most of his London underworld bosses are turning up: in a body bag in a shallow grave?
