Anne Rogers is the secretary to Kenneth Bixby, the author of many best-selling novels. On a lecture tour, he meets Julie Wilson, an old girl friend, who believes that she is the inspiration for the heroine of Bixby's latest novel. Having heard about Bixby all during his marriage, Julie's husband Harvey hates him, even though he has never met him. Julie is determined to rekindle their romance, and while she entertains Bixby, Anne takes care of her outraged husband. Julie's younger sister Elizabeth and her stuffy fiancé, Arthur Westlake, are aware of Julie's intentions and are determined to prevent a scandal. After Bixby's rendezvous with Julie, Anne arranges to meet him on the night train, where she is joined by Harvey, Elizabeth and Arthur. Julie is also on the train, and in order to avoid Elizabeth, Harvey and Arthur, who are waiting in her compartment, she spends the night with Bixby. When Harvey hears this he decides to sue for divorce. Even though Bixby swears that nothing happened, Anne is jealous and washes her hands of the author. Bixby has no intention of marrying Julie and tries several ruses to discourage her. Finally, Anne gives in to Bixby's pleading and tells Julie that another woman was the model for the novel's main character. This information sends Julie back to her husband, and Bixby convinces Anne that she loves him and should take him back.
