The first of three TV movie versions of the French play by Robert Thomas, Piège pour un Homme Seul (Trap for a Single Man); which itself was based on the Indian films Sesh Anka and Puthiya Paravai; which were inspired by the British film, Chase a Crooked Shadow. (The later TV movies, both American, were One of My Wives is Missing and Vanashing Act.) In this version, however, the would-be single man is a would-be single woman. Instead of man on honeymoon with his wealthy new wife, who disappeared after an argument and reappears - as an impostor; Janet Leigh is a woman on honeymoon with her wealthy new husband, who disappeared - but now an impostor is claiming to be her husband. She protests that this stranger is not her husband but his papers and identity photos are all in order. There is every indication that he is, indeed, the husband he claims to be. But he can't be. Can he?
