It is 1949, and 'The Smoke' remains tarnished with shattered, abandoned buildings and bombsites. Its the perfect backdrop for Jethro - honest Cockney cat burglar - to redistribute the wealth of the upper classes.

Its deemed a homicide when the jewels are discovered missing, and Jethro sets off on a search into Londons dark underworld to find out who is trying to frame him.
