The Guillotine examines the fascinating and bizarre history of the "national razor" that started out strictly for execution and then became a source of entertainment and amusement. In Scotland they called it "the Maiden," in England "the Halifax Gibbet," and in France "the Machine," "the Widow," and "the Guillotine." It existed for hundreds of years, but found its home in France during the French Revolution and the Reign of Terror when nearly 20,000 men, women and children died beneath its blade.
