This Shadow is no mind-clouding vigilante, but a mysterious criminal genius who uses "radio death rays," gyrocopters, and other exotic inventions as he and his henchmen search for priceless jewels stolen from Czarist Russia. Is the owner (Bela Lugosi) of an eerie wax museum the culprit, or could it be someone else? Henry B. Walthall, Viva Tattersall, and Malcolm McGregor co-star in this suspense thriller culled from the Mascot Pictures serial. 60 min. Standard; Soundtrack: English. Plays All Regions.
