Jack, the owner of a failing bookshop in a picture-postcard country town near London, is embezzling from a client. Thea is a philosophy lecturer with a taste for pinching cash. There's something amiss with their marriage, but an occasional spot of larceny provides the frisson to keep it going, as well as the funds for the kids' school fees. But things start to go badly wrong when an old lover turns up demanding a slice of the action. Could you live with a would-be murderer? This is the question for Thea and Jack in this fast-moving psychological drama with an undercurrent of black comedy.
