The Crimson Ghost (1946)

The Crimson Ghost--attired in black hood and cloak, skull mask and surgical gloves--skulks to an abandoned mansion and informs his henchmen, Louis Ashe (Clayton Moore) and Bain (Rex Lease), of his plans to seize the Cyclotrode, a device invented by Dr. Chambers (Kenne Duncan), that is designed to detect--and repel--atomic bomb attacks. The Crimson Ghost intends to use the Cyclotrode as an offensive weapon for sabotage and extortion via its ability to stop any electrically-controlled mechanism.
