Lucinda Purefoy is young, well-connected and wants to 'pay her debt to society'. To that end she joins SCRAP (Social Carers, Reformers and Praeceptors), an organization that allows girls like Lucy to mentor ex-cons.
Which is how Lucy comes to meet a career burglar called Terry, on the street outside Wormwood Scrubs. Though their initial meeting is inauspicious - it ends in a row in Burger King - the pair gradually begin to overcome their differences. However, it is soon unclear who is proving to be a greater influence on whom - angelic Lucy or rough-and-ready Terry . . .
