 "Gals, Incorporated" is a nightclub sponsored by elderly playboy Cornelius Rensington III (Leon Errol) that features Glen Gray and the Casa Loma Orchestra, with all the other employees and entertainers being beautiful girls. Molly (Grace McDonald) is president of the corporation and Gwen (Harriet Hillard) is head of the executive staff. Jennifer Rensington (Minna Phillips), 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 (David Bacon), Cornelius  son by a former marriage. Molly, while attracted to Bill, has to 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.
