Synopsis by Janiss Garza
Clive Brook has a dual role in this British-made melodrama, which has a serial-like feel. A banking syndicate backs the plan of Anthony Barraclough (Brook) to obtain a radium concession in the Balkans. He needs to exercise his option by a certain date, but Hugo Van Diest, the head of a rival ring (Norman Page), is just as determined that he fails in his mission. Then one of Barraclough's friends meets Richard Altar (Brook again), an exact lookalike for Barraclough. Altar takes the offer to become Barraclough's double and is kidnapped by Van Diest's henchmen. He is tortured in hopes that he will give out the location of the radium field. But he keeps his mouth shut while Barraclough completes his task. Altar's identity is revealed, and one of Van Diest's men attacks the real Barraclough in a dirigible which explodes. Both Barraclough and his assailant parachute to the ground and the chase continues. Auriole Craven (Catherine Calvert) helps Altar escape his tormentors, and Barraclough returns to London in time. He shares his interest in his enterprise with Altar, who also has won Auriole's heart.
