Arthur Clutten (Norman Wisdom) is an expert safecracker who masterminds every heist for the crime syndicate he belongs to. But when he witnesses the brutal methods of persuasion being meted out the gang's leader, Ignatius Smith (Bernard Hill), Clutten decides to quit the gang. However, he soon realises that the gang would rather see him dead than leave them, and so he decides to steal some documents that would incriminate the criminal mastermind Edward Ross (Simon Ward) and expose his honest facade. Having sent his family into safe-hiding, Clutten goes on the run. The gang put a contract out for a hit man to kill Clutten and retrieve the missing documents but have they under-estimated the nervous but desperate former criminal? When the gang kidnaps his daughter Sarah (Chloe Annett), and offer her in return for the incriminating documents, Clutten has a stark choice: to stay on the run, or give himself up in order to save his daughter's life.
