A multimillionaire Silas Gyde was killed by an anarchists bomb and Jack Norman found himself Silas Gydes sole heir and the richest man in New York. The inheritance included a warning from his benefactor about an elaborate protection scheme promising to protect the wealthy from anarchists, in which Gyde had declined to enroll. Jack enlists a out-of-work actor to take on his own identity, while he, in the guise of Jack Normans secretary, works furiously behind the scenes to break up the gang and unmask their leader Mr. B.
