Wealthy Mary Haines is unaware her husband is having an affair with shopgirl Crystal Allen. Sylvia Fowler and Edith Potter discover this from a manicurist and arrange for Mary to hear the gossip. On the train taking her to a Reno divorce Mary meets the Countess and Miriam (in an affair with Fowler’s husband). While they are at Lucy’s dude ranch, Fowler arrives for her own divorce and the Countess meets fifth husband-to-be Buck. Back in New York, Mary’s ex is now unhappily married to Crystal who is already in an affair with Buck. When Sylvia lets this story slip at an exclusive nightclub, Crystal brags of her plans for a still wealthier marriage, only to find the Countess is the source of all Buck’s money. Crystal must return to the perfume counter and Mary runs back to her husband.
