In Wilder's smutty low comedy, Dean Martin has little trouble easing into the role of Dino, a womanizing pop singer with a yen for the grape. En route to Hollywood after a Las Vegas gig, he stops in a small Nevada town, where his arrival is considered a piece of extraordinary fortune by amateur songwriters, music teacher Orville J. Spooner (Ray Walston) and mechanic Barney Milsap (Cliff Osmond). To guarantee Dino's presence and a hearing for their songs, Barney makes a few alterations in his car, while Orville offers his house for the night. But when he learns of the singer's overwhelming need for sex, Orville gets his attractive wife Zelda (Felicia Farr) out of the house and persuades local hooker and waitress Polly the Pistol (Kim Novak) to take her place in case the singer needs special attention. Even so, when Dino makes the predicted moves on Polly, the music teacher still is overwhelmed by jealousy and throws the bewildered singer out of the house. Dino seeks refuge in a nearby bar, only to find Zelda drowning her sorrows.
