In 1792 during the Reign of Terror of the French Revolution, a secret league of brave Englishmen are rescuing French aristocrats from the guillotine. The leader of this secret society is a mysterious English nobleman known only as the Scarlet Pimpernel, whose signature sign is a humble Anagallis arvensis. In society he hides his identity by posing as the wealthy but foppish and seemingly empty-headed Sir Percy Blakeney (Anthony Andrews). After rescuing the Count de Beaulieu and his family, Percy is introduced to the beautiful French actress Marguerite St. Just (Jane Seymour (actress)) through her brother, Armand (Malcolm Jamieson), whom he rescued from an attack. Percy is attracted to Marguerite, but she is in a relationship with Paul Chauvelin (Ian McKellen), an agent of Maximilien Robespierre. Due to the Scarlet Pimpernel's past successes, Chauvelin is assigned to discover his identity and capture him.
