Roger Moore plays a conservative, ambitious City business man who is involved in a car smash in which he was guilty of reckless, out-of-character driving. From the moment of his recovery strange things begin to happen. He is apparently in two places at once. He apparently indulges in sharp business practice. He is apparently having an affair with a girl who he has only once met, and casually.The uncanny situation begins to prey on Moore’s mind. Has he an unscrupulous double? Or is it all a figment of his imagination? These are the headaches that prey on Moore and add up to a tense riddle. Hildegard Neil as Moore’s wife has only a cardboard role, but handles the disintegration of her marriage competently.
