The Dorothy Madison Company of New York City, headed by Helen Murphy, is a service that will solve any problem for its subscribers. One of Helen's main clients is Scott Robinson, an engineer and bridge builder. He wants to write a cook book, so Helen finds a chef, Babenko, to help him with his experiments. Robinson is so happy with Helen's work that he turns the management of his flighty daughter Audrey over to Dorothy Madison. Although the business is very successful, Helen has grown tired of bossing men around and would like to find a man with a mind of his own. While on a job to prevent a client's nephew, Robert Wade, from coming to New York, she mistakes another man for her target and falls in love with the real Bob, whose name she has not learned. Having spent a lifetime being bossed by his aunts, Bob is determined never to be under the thumb of any woman. Believing that his nephew has been dispatched by Helen, Bob's uncle is furious when Bob appears in his office and sends him off to Dorothy Madison, where Helen learns of her mistake. From behind the scenes, she asks Robinson to take a look at Bob's plans for an expensive tractor, and he is so pleased with them that he offers Bob space to work in his machine shop. Audrey is taken with Bob too, but he is in love with Helen, not realizing that she is the brains of Dorothy Madison. Meanwhile, Bob is tired of being organized by Dorothy Madison, especially when Helen, disguising her voice, calls to warn him against Audrey. After Audrey mistakenly thinks that Bob has proposed to her, a delighted Robinson makes the announcement to Helen. Helen rushes to Bob's apartment and confesses that she is Dorothy Madison. Bob is so mad that he tells her he is going to marry Audrey after all. Completely unaware of Helen's relationship to Bob, Robinson asks for her help in planning the wedding. At the same time, Bob learns that Babenko is actually a Russian prince. Knowing of Audrey's interest in royalty, Bob tells her about Babenko's background. Things end happily when Audrey leaves Bob at the church to marry Babenko, and Bob marries Helen instead.
