At a dance given by Earl Dexter, his wife, for the gratification of a whim, wears a beautiful pearl necklace recently purchased by Viscount Acheson. Craig Dare, who is a gentleman thief, makes love to Earl Dexter's wife, and at the same time succeeds in stealing from her the pearl necklace and handing it out of the window of the house to Tony Oscaros, a chauffeur, who is none other than Dexter, who is leading a dual life. The party ends in confusion at the announcement of the loss of the necklace. Craig Dare learns that Viscount Acheson, who carries with him a considerable sum of money, is going to be at an inn (owned by Dexter's father) in the neighborhood. Dare goes with Acheson to the inn and allows him to fall into the hands of Tony Oscaros and his gang. Shortly before this happened, Earl Dexter comes to the inn to see his father, who, however, is absent at the time. Dexter's father returns to his inn in time to find the murdered Acheson, and see Tony Oscaros dashing out of the house. By a peculiar coincidence, Oscaros looks so much like Earl Dexter that even his father is deceived by the resemblance. Later, Earl Dexter is accused and convicted of the murder of Acheson. At the last moment. Tony Oscaros' little boy recognizes the fact that Dexter is not his father, and so gives the clue to the guilt of Tony Oscaros. The police follow up the clue and after finally encounter and capture Tony Oscaros.
