What do you do when you have a beautiful house, two great children, and a Marriage on the Rocks? If you're bored Val Edwards (Deborah Karr), you swap your fuddy-duddy hubby Dan (Frank SInatra) for his swingin' bachelor best friend Ernie (Dean Martin) - and watch the spraks fly. Ol' Blue Eyes breezes through this romantic comedy romp at the head of an all-star cast. Along for the laughs are frequent Sinatra co-stars Martin, Cesar Romero, and Tony Bill, plud daughter Nancy Sinatra and Kerr. The fun starts when the Edwards take a second honeymoon in Mexico and fall into the hands of the quickie-divorce/quickie-marriage lawyer Romero. Faster then jumping beans, everybody's unhitched, rehitched, confused, confounded, and cohabitating. But Dan has the right attitude. "We had a bad marriage", he says. "Let's have a happy divorce!"
