The thirteenth film in the Carry On series and one of the only two installments in the franchise to have not had the Phrase "Carry On" in its title during its original release. Set around the French revolution, the film is a spoof of The Scarlet Pimpernel, with Sid James leading the way as The Black Fingernail. Leading the villains is Kenneth Williams as Robespierre's chief of secret police, overly pompous Citizen Camembert.
