Former actor Pop O'Malley, now the elderly doorkeeper at a theater, takes a paternal interest in Eileen, a struggling young chorus girl. Upon learning that Eileen has exhausted her funds, Pop takes her into his home, buys her a new wardrobe, and gets her a job at the theater. Larry Taylor, millionaire backer of the show, also takes an interest in Eileen, but Pop is suspicious of his intentions. Despite Pop's warnings, Eileen falls in love with Larry and accepts his invitation to a weekend party at his country estate. Pop follows her, and when she refuses to leave with him, the old man slashes his wrist with a broken bottle. Larry summons a doctor and offers a transfusion of his own blood to save Pop's life. Later, Pop consents to the romance after Larry reveals that he wants to marry Eileen.
