Black Dragons

At the height of World War II, several industrialists are found dead at the Japanese Embassy in Washington, D.C. The industrialists, who tried to subvert American war efforts, were murdered by Monsieur Colomb (Bela Lugosi), who is staying at the home of another noted industrialist, Dr. Bill Saunders (George Pembroke). Saunders doesn't realize his life is in danger, but a federal agent, Richard Martin (Clayton Moore), soon arrives on the scene to unravel a shocking conspiracy.
