Sailor Ted meets at the Lonely Hearts Club of his friend Gunny's wife, Jenny, a girl, Nora Paige, and falls in love. Nora wants to become a dancer on Broadway. Ted rescues the Pekinese of Lucy James, a Broadway star during a public relations campaign on his submarine. Lucy falls in love with Ted, and Ted is ordered by his Captain to meet her in a night club, in spite of the fact that he has a date with Nora. Nora, who lives with Jenny and her and Gunny's daughter, doesn't want to hear anything from Ted, after she spotted a picture of Ted and Lucy in the morning paper. Lucy convinces her manager Dinehart to stop the press campaign and tells him that she would leave the production, if another photo or article of her and Ted is published. Nora has become her understudy, and she begins to think her behaviour to Ted over. Suddenly she is fired after Dinehart told her to dance a number Lucy James called undanceable. But when Ted is told the whole story, he knows what to do.
