While vacationing with his wealthy and much-older wife Gladys (Vivienne Segal), Ray Marschand (Robert Horton) meets and falls in love with Nyla Foster (Anne Francis), the young daughter of trailer-camp owner Floyd Foster (John F. Hamilton). Deciding that he'd be better off trading his wife for a younger model, Ray begins plotting Gladys' demise. The episode climaxes as Ray and Gladys embark on a fateful fishing excursion, with the requisite surprising results. This final episode of Alfred Hitchcock Presents' fifth season was originally telecast two days before the series switched networks and time slots for the inauguration of season six. ~ Hal Erickson, Rovi
