What if the Dauphin of France managed to escape the Reign of Terror during the French Revolution? That's the premise of the opulent British swashbuckler Dangerous Exile. Louis Jourdan stars as the Duc de Beauvais, who manages, at great personal sacrifice, to smuggle the son (Richard O'Sullivan) of King Louis XVI into England. The boy takes up residence in Wales, where he is protected by local lass Virginia Traill (Belinda Lee) and her wealthy Aunt Fell (Martita Hunt). When time comes for the boy to return to France, he refuses--but local newspaper editor Patient (Finlay Currie), a spy for the French revolutionaries, has other ideas. Keith Michell, future star of TV's Six Wives of Henry VIII, is well cast as a French Republican with whom the Duc de Beauvais must inevitably cross swords.
