As Rob reaches the end of a seven year stretch inside, he winds up in an open prison in Brixton. Each morning, he exits the prison gates and spends the day a local charity shop. All he needs to do is keep his nose out of trouble and soon he'll be out for good. One morning, Rob notices a well-dressed woman trip over. He helps her up and despite coming from very different worlds, the pair slowly become acquainted. But who exactly is this woman who seems to have a growing interest in him? Rob must be very careful - one false step and it could set him back years . . .
