Stewardess and ex-nurse Diane Sullivan is happy with her husband Martin, who runs a London restaurant, and cute son Jack (8). However, when passenger Mark Landucci, once her patient, asks her to play his wife to smooth out a business deal for his Italo-Scottish father's marble firm in Bologna, she pretends to be single and seduces him. After a few months she commits bigamy. It gets ever harder to keep the secret, even in two countries and helped by her single, philandering colleague Karen. A drama waiting to happen?
