Reign of Terror

Exiled to Austria, former French military commander the Marquis de Lafayette (Wilton Graff) orders Charles D'Aubigny (Robert Cummings) to destroy the impending dictatorship of the bloodthirsty Robespierre (Richard Basehart) by assuming the identity of his corrupt new prosecutor. With the help of opposition leader François Barras (Richard Hart) and his former lover, Madelon (Arlene Dahl), D'Aubigny goes in search of Robespierre's enemies list, written in a small black book that has vanished.
