This comedy concerns Polly Emerson, a pretty young thing who wants to be an actress. Polly's husband, Don, is a successful advertising man, who yearns to be a playwright and has a shelf of unproduced plays to his credit. Don understandably isn't too happy when Polly comes home with Deerfield Prescot, a very young guy who has written Broadway's next musical hit—or so he tells Polly and Don. He's decided that Polly is just the person to star in his show, so Polly's life, and consequently Don's, is taken over by Deerfield, who moves into their apartment to put the finishing touches to his masterpiece. Gloria, a chum of Polly's and a beautiful divorcee, arrives at the same time, and there's an interfering maid (called Juliet) ever present, not to mention Don's secretary, Martha, who's disillusioned with life and men. This assorted cast of characters raises havoc with Polly's and Don's life, much to the delight of the audience, and it isn't until a Vassar girl named Penelope arrives on the scene that Deerfield is properly straightened out. He and Penelope leave in pursuit of happiness; Gloria leaves in pursuit of her next husband; and Polly and Don, alone at last, decide to concentrate on their coming baby rather than a play. All is quiet, peace reigns, when still another visitor appears to take over the household—Don's mother-in-law!
