According to old Mr. Barry's will, if his son Jim fails to marry, the vast Barry estate will revert to the O'Maras. When one night Jim, an irresponsible drunk, falls down the stairs and is given until morning to live, Mrs. Barry, in order to protect the property from the O'Maras, pleads with Molly Shawn to marry her son. Molly, although in love with Barney Malone, agrees out of a sense of indebtedness to the Barry family, and the two are married. Much to everyone's surprise, Jim recovers and Molly pines for her sweetheart Barney until it is discovered that the priest who performed the ceremony was really a criminal who, to escape the law, had disguised himself in priests' robes. Overjoyed, Molly is disentangled and now free to marry Barney, the man she loves.
