It features regular team members Sid James, Kenneth Williams, Jim Dale, Charles Hawtrey, and Joan Sims.

Whilst the French aristocracy is losing their heads (literally), two bored English noblemen, Sir Rodney Ffing (pronounced "Effing") and his best friend Lord Darcy Pue, bored with the endless rounds of country pursuits, decide to have some fun and save their French counterparts from beheading by the guillotine.

During his escape from France, Sir Rodney meets his true love, Jacqueline, leaving her with a silver locket containing a set of his mother's false teeth.

Foppish Sir Rodney challenges Camembert to a rigged duel in order to get a head start on his journey to Paris to rescue Jacqueline.

On arrival in Paris, the Fingernail discovers that Jacqueline has been moved from the Bastille to the Château Neuf, the former home of an avid art collector and member of the aristocracy, recently presented to Citizen Camembert - by himself.
