Eighteen year old Christine Novak's ambition to be a nurse is wrecked when she is injured in a car accident. Casey, her male cousin, arrives in England to help her recover. Christine persuades him to wear her nurse's uniform, a dress, apron and cap while he looks after her. They are so alike that when wearing makeup Casey could even be Christine and she hatches a plan to persuade him to begin nurse training so that she can take over when she recovers. Sharing a room in the nurse's home with an undercover policewoman, a simple plan becomes a dangerous and tortuous rollercoaster of sex and crime as the two young nurses join forces both in and out of bed.
