Jim "Lucky" Moore (Allan Jones), an insurance salesman, comes up with a novel policy for his friend, Steve (Robert Cummings): a 'love insurance policy', that will pay out $1-million if Steve does not marry his fiancée, Cynthia (Nancy Kelly). The upcoming marriage is jeopardized by Steve's ex-girlfriend, Mickey (Peggy Moran), and Cynthia's disapproving Aunt Kitty. The policy is underwritten by a nightclub owner, Roscoe (William Frawley), who sends two enforcers - Abbott and Costello - to ensure that the wedding occurs as planned.
