TV comedian Steve Coogan makes the move to the big screen with this crime caper. Parole officer Simon Garden (Coogan) is transferred from Blackpool to Manchester and soon finds himself on the trail of corrupt cop Burton (Stephen Dillane). Burton then realises what Simon is up to and threatens to frame him for a recently committed murder if he doesn't leave it alone. The proof of Simon's innocence is a CCTV tape which shows Burton committing the murder, but the cop has the tape locked safely away in a bank vault. So the resourceful Simon rounds up a gang of inept ex-criminals, all former clients of his, and begins drawing up plans to break into the vault and retrieve the evidence.
