Stanley Stanfield, son of the founder of a great newspaper, and Carl Van Dorn, electrical genius, have invented a Vanishing Ray with which they hope to expose Eade Barnett, whose persecution of Stanfield's father caused his death

Stanfield raced ahead of the train, eluded his pursuer, and hid in Van Dorn's mountain laboratory. Barnett's estranged daughter telephoned Stanfield that Cadwell, for whose murder he was sought, was alive, and she asked him to call that evening.

With Van Dorn's electric torch, Gloria burned open the vault door and rescued Stanfield. Needing time to work out his scheme to get control of the Tribune, Barnett imprisoned McDonald on a rocky, inaccessible island, intending to use McDonald's absence as an excuse for postponing the stockholder's meeting.

Having failed in their attempt to fly to McDonald's rescue, Stanfield and Gloria returned to Van Dorn's laboratory. To their surprise, McDonald telephoned from his office and they hurried to see him. Van Dorn, worried, set a trap for intruders before his vault, then learning from McDonald that Stanfield had gone with Gloria to Barnett's office, taking his "Destroying Ray," followed them.
