"Gals, Incorporated" is a nightclub sponsored by elderly playboy Cornelius Rensington III that features Glen Gray and the Casa Loma Orchestra, with all the other employees and entertainers being beautiful girls. Molly is president of the corporation and Gwen heads the executive staff. Jennifer Rensington, Cornelius' sister, threatens to cut off his share of the family income unless he settles down and gets married. The girls persuade the unwilling Molly to pose as Cornelius' wife. The sister arrives with Bill Rensington, Cornelius' son by a former marriage. Molly, while attracted to Bill, must play out her role and Bill, thinking she has married his father for his money, turns his attention to Gwen, a scheming mercenary. Gwen arranges for Bill to cross the state line with her and get married, but Cornelius and the other girls catch up before the ceremony can be performed. Bill is told the truth about the hoax, and gathers Molly up in his arms.
