Dr. Judd Lewis, a Park Avenue practitioner, keeps on top of his busy schedule due to the efforts of his assistant, Miss Stephens, whom he calls "Steve" and treats as if her attractiveness is not something he notices. When Ina Heath, a wealthy socialite, injures her shoulder after she is thrown from a horse in the park, Judd takes an interest in her. After she does not show up for him to check the shoulder's progress, because, she says, she does not want to be like the many other women patients who clutter his office seeking his attention, Judd locates her at a club. As they dance, Judd learns that she took her bandage off because it itched, so he takes her into the kitchen and, using black kitchen tape, replaces the bandage. They are interrupted when Judd receives a message that he is needed at the hospital. After an exhausting operation, Steve massages Judd's head as he relaxes resting his head on her lap. Later, as Judd removes Ina's bandages, he flippantly proposes marriage, but then reveals that he means it, and they get married in New Rochelle. That night, Ina is introduced to the life of a doctor's wife when Judd's colleague, Dr. Therberg, calls for him to quickly come for a consultation regarding a dangerous operation. Although he promises that he will not be gone long, Judd conducts the operation himself and ends up sleeping at the hospital. Soon, he and Ina have a wonderful honeymoon in Europe, but upon their return, he stops by the office to deliver gifts and then leaves immediately for the hospital to perform an operation, while Ina, whom he has forgotten, waits in a cab. When he returns, she surprises him by not throwing a tantrum or bawling him out, which he expects that a wife left in that situation would do. One day, after Ina sees Judd from a distance with Steve, she becomes a bit concerned and asks Steve to lunch. Ina confesses that she thought "Steve" was a hulking interne and asks Steve if she is in love with Judd. When Steve replies that she is terribly happy working with him, but that it never occurred to either of them to think of a romance between them, Ina is satisfied. Later, however, when Judd kisses Ina in Steve's presence and talks in a passionate manner, Steve becomes upset. After another operation, as Steve massages Judd's head, she kisses him, then apologizes and walks away. She quits her job that day. Without Steve, Judd's manner changes abruptly as he becomes aloof and quick with Ina. When Ina finds out that Steve has left, she visits Steve in the country and learns that Steve did not realize that she was in love with Judd until their luncheon and that she quit because she didn't want to become a frustrated woman. Candidly, Ina reveals that now that she knows this, she does not want Steve to return. Soon Judd returns from work one day in lifted spirits. When Ina learns that Steve has returned to her job, she asks if Judd isn't in love with her. Although he denies that he is, she is afraid that he might be lying to himself. Ina leaves for Reno and Judd gets drunk. Steve finds him and takes him to her apartment, where she puts him to bed. As she prepares to sleep on the sofa, Ina, who turned back when she reached the airport, enters and accuses her of not losing any time. The phone then rings, and they learn that Judd's young friend Red has been hit by an automobile and won't let anyone but Judd operate on him. Together the women sober Judd up. The operation is a success, and afterwards, neither woman wants to give Judd up. Judd realizes that he cannot live without either of them, so they decide to try to forget that the luncheon, which put the idea of love into Steve's head, ever happened.
