Ray and Polly Cutler (Showalter and Peters), on a delayed honeymoon at Niagara Falls, find their reserved cabin occupied by George and Rose Loomis (Cotten and Monroe). Rose tells them that George is asleep and has recently been discharged from an Army mental hospital after his war service in Korean War. The Cutlers politely but reluctantly accept another, less desirable cabin, and so the two couples become acquainted.
