Comedy double act Jerry Lewis and Dean Martin star in this Navy-set musical comedy. Because of a mix-up, Melvin Jones (Jerry Lewis) is inducted into the Navy, despite his numerous allergies. When appearing on a TV show sponsored by a lipstick manufacturer, a series of bizarre circumstances cause him to be perceived as an irresistibly good kisser, and he is undeservedly hyped by the media as 'Mr Temptation'. His shipmates bet their pay that he can get sexy French chanteuse Corinne Calvet (appearing in the film as herself) to kiss him. Despite his allergy to kissing girls, he tries not to let them down - even though it threatens his relationship with his erstwhile girlfriend Hilda (Marion Marshall).
