After the death of his father, Peter Judson Kirk, Jr. vows that from now on, he will do as he pleases, which is mainly to chase beautiful women. He meets his match, however, in attractive physician Dr. Helen Hunt, with whom he hitches a ride to Los Angeles after his car is demolished in an accident. Peter is delighted when Helen's car needs a repair that will require them to spend the night at a nearby motel. Even though he has only known Helen a short time, Peter immediately proposes marriage, but Helen turns him down, stating firmly that she wants a career, not marriage. When Peter insists that marriage would not interfere with her profession, Helen succumbs to his entreaties and marries him. In Los Angeles, Peter's resolve is tested immediately when a romantic dinner at home is interrupted by an emergency call. After several such calls, Helen is summoned to a delivery and is gone for the rest of the evening. When she finally returns, she mentions the name of a former suitor and current patient, Vandemer, and Peter instantly becomes jealous. The next morning, Peter's jealousy is again roused when he remembers that Helen accepts male patients. He hurries to her office and there overhears her laughing with a male patient and breaks into the examining room. Once again he must apologize for his jealousy, but that same night, when Peter and Helen go dancing, they encounter Van, and Peter challenges him to a fight. A few days later, Van throws a surprise party for Helen and Peter, but Peter misunderstands and makes a jealous scene. Furious, Helen accuses Peter of laziness and charges that he does nothing because he is afraid of failure. After she leaves him, Peter tries various jobs, but succeeds at none of them. Later, a newsboy is badly injured when he saves Peter from being run over by a car. At the hospital, Dr. Heimer, a highly-qualified foreign surgeon, is unable to operate because he has not completed the required American internship. Peter induces him to operate anyway and later asks for Helen's help in overturning the internship requirements. Helen explains that the internship laws ensure that doctors trained abroad will meet U. S. standards and that what is really needed are more hospitals where foreign doctors can work as interns. Peter then builds a new hospital. Helen, meanwhile, has gone to Reno for a divorce. Convinced that he is now a man that Helen could love, Peter flies after her, but she tells him that she plans to marry Van, who does not have a jealous bone in his body. When Van learns that Peter is in Reno, however, he reveals that he is just as jealous as Peter. Disgusted with both men, Helen is ready to leave, but the hotel maid persuades her that jealousy means the men really love her. Realizing that the maid is right, Helen reconciles with Peter.
