Glover is charmed by new admission Harry Bridgewater - until it transpires that he is a prisoner who has come in for an operation with a guard in attendance. Having tried to pass himself off as a hardened criminal, Bridgewater has to admit he is merely a getaway driver but asks the patients to cover for him whilst he escapes – for a night – to be intimate with his wife. They agree and persuade Thorpe to assist them but will the convict really return?
