Sir Percy is always ready to make a wager. However, betting on the outcome of the Pimpernel's latest escapade could be dangerous - and even cost him his freedom.

The Pimpernel goes back into danger to rescue a serving girl. Ginette is a lovely and spirited young woman and he finds himself falling for her and wondering what a different life would be like.

Chauvelin's scheme to capture the Princesse de Monsantes before she can escape to England succeeds and she and her servant fall into his trap. Sir Percy hears about it and hatches his own scheme, rescuing the Princesse and her servant from under Chauvelin's nose and smuggling them to England. Outraged, Chauvelin travels to England, planning to kidnap the Princesse and bring her back to France. Meanwhile, the Prince has hired a Chinese decorator to remodel a wing of the palace, and Sir Percy decides to use the man in his plan to thwart Chauvelin's plot.

Hearing that the Scarlet Pimpernel is being impersonated in France by an Englishman who is robbing and murdering French aristocrats, Sir Percy sets a trap to catch the imposter.

The lovely Comtesse la Valliere, formerly a spy for Chauvelin, changes sides when she learns of the impending execution of dozens of moderate French revolutionaries. Teaming with the Scarlet Pimpernel and his men, the Comtesse plans to rescue the condemned men - from under Chauvelin's nose.

Sir Percy discovers that Chauvelin is blackmailing the banker Rothstein by holding his daughter, Rachelle, captive. He hatches a plan to fool the doctor treating Rachelle into unwittingly help her escape Chauvelin’s clutches and reunite her with her anxious father.

The Abbey of Nanterre has been plundered by Chauvelin, and many of its monks lie dead. Sir Percy decides to rescue the remaining monks, including the Father Guardian, who Percy discovers to be quite a handful.

Giving one of Sir Percy's agents false information, Chauvelin hopes to lure the man he thinks is the Pimpernel into the open. He achieves his aim but is astonished when a 'simple minded' farmer's boy (the Pimpernel in disguise) arrives.
