Sol Glass (Ferdinand Gottschalk) owns a clothing manufacturing company struggling to survive in the midst of the Great Depression. Like his competitors, Glass employs "customer girls" to entertain out-of-town buyers. However, his clients have become tired of his hard-bitten "gold diggers" and have started taking their business elsewhere. Tommy Nelson (Regis Toomey), one of his salesmen, suggests that they use their stenographers instead. Glass decides to give it a try.
When buyer Luther Haines (Hugh Herbert) sees Tommy's secretary and fiancee, Florence "Flo" Denny (Loretta Young), he wants to take her out. However, Tommy manages to steer him to the curvaceous Birdie (Suzanne Kilborn) instead. Later, with Birdie sick, Tommy reluctantly lets Flo go on a date with another buyer, Daniel "Danny" Drew (Lyle Talbot). They have a nice time together, but she is shocked when she finds out Danny expects sex. A contrite Danny apologizes and tells her that he has fallen in love with her. He has to go on a business trip, but telephones and writes to her regularly.
Meanwhile, Flo's friend, fellow employee and roommate, Maizee (Winnie Lightner), shows her that Tommy is cheating on her with Birdie. She ends their engagement.
To keep her self-respect, Flo tells Glass that she will not go out with any more buyers. When he threatens to fire her, she quits.
Danny returns and takes Flo to dinner. Then, spotting Haines at another table, he asks her to help convince the last holdout to a merger to sign an important contract, the biggest deal of his life. She is disappointed by his request, but agrees to do it. She goes to dinner with Haines, but cleverly arranges with Maizee to have Haines' wife (Helen Ware) and daughter show up. Haines has to go along with the pretense that he is conducting business, and signs the contract.
When Haines later complains about Flo's methods, and claims that she and Tommy are living together, Daniel suspects that she is not as innocent as he believed, so he drives her out into the country to the mansion of his friends. Nobody is home, but he coaxes her inside and tries to force himself on her. Flo tries to get away, but finally stops resisting. However, when she asks him if that is all she means to him, Danny stops before anything happens. She leaves, only to run into Tommy, who had followed the couple. He also believes she is selling herself. Danny, overhearing their conversation, realizes that Flo is innocent, and forces Tommy to apologize. Danny begs her to marry him. After she whispers in his ear, he picks her up and carries her back into the mansion.
