Jack-of-all-trades Luke Hawkins, of the western town of Lariat, falls in love with Mary Darling, the leading lady in a traveling theatrical troupe (of the old-fashioned "mortgage melodrama" variety). He follows her to New York, takes another series of jobs, and finally works as an extra in Mary's new production. Just as the play is about to flop, Luke recognizes Mary, and his rush to take her in his arms turns the show into a hit.
