An ad exec in disguise courts his pretty female competitor.

Though they have never met, Jerry Webster and Carol Templeton, account executives with rival advertising agencies, are sworn enemies. Jerry's practice of using liquor and chorus girls to land clients galls the hard-working and conscientious Carol. When she reports him to the Advertising Council, Jerry induces Rebel Davis, a sexy nightclub performer he uses to charm his prospective clients, to testify on his behalf. As a reward for helping him win an acquittal, Jerry names Rebel the VIP girl and films a series of commercials for a nonexistent product. Unfortunately, Jerry's boss, a hopeless neurotic named Peter Ramsey who is apron-stringed to his analyst, puts the commercials on television--and VIP is launched. Frantic, Jerry engages an eccentric scientist, Dr. Linus Tyler, to invent a product that can be marketed as VIP. Carol visits Linus in an attempt to steal the account away from Jerry. When she arrives at his laboratory, she encounters Jerry, mistakes him for Linus, and announces that she will stop at nothing to get the account. Delighted by both the attractiveness of his rival and the chance to ruin her, Jerry pretends to be the scientist and allows Carol to wine and dine him. Just as he is about to complete his triumph by seducing Carol, she learns the truth. Appalled, she once more reports him to the Advertising Council, this time for advertising a nonexistent product. Jerry, however, arrives at the hearing with VIP, a mint-flavored candy he offers to one and all, including Carol. There is only one drawback: each one of Linus' wafers has the same effect as three triple martinis. The next morning, Jerry and Carol wake up in a motel with a marriage certificate hanging on the mirror. The horrified Carol has the marriage quickly annulled while Jerry flees to his firm's west coast branch. They are reunited and remarried 9 months later, however--in a hospital maternity ward.
