Dulcy, the slightly wacky but well-meaning fiancée of Gordon, an anxiously up-and-coming business buff, is bent on hostessing a party to bring her future hubby’s potential partners into line. The crusty Mr. Forbes is the object of their fawning flattery, which backfires at every turn; and the obstreperous Van Dyke is a mad financier whose favor is finally surrendered so as not to interfere with his lechery. But it is the scatterbrained Dulcy who in the end does all the wrong things for the right reasons and secures her fiancé’s financial future and her own “world-without-end” bargain.
