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 Kerr), you swap your fuddy-duddy hubby Dan (Frank Sinatra) for his swinging-bachelor best friend Ernie (Dean Martin) and watch the sparks fly. Joining Ol' Blue Eyes in this romantic romp are frequent costars Martin, Cesar Romero and Tony Bill, plus daughter Nancy Sinatra and From Here to Eternity castmate Kerr. The fun starts when the Edwardses take a second honeymoon in Mexico and fall into the hands of quickie-divorce/quickie-marriage lawyer Romero. Faster than jumping beans, everybody's unhitched, rehitched, confused and confounded. Dan has the right attitude. We had a bad marriage, he says. Let's have a happy divorce!
