The Scarlet Pimpernel rescues a Baroness from Chauvelin, but she is reluctant to leave because Chauvelin has her son. The Scarlet Pimpernel must rescue the boy and not give away his identity as Sir Percy Blakeney.

In his strangest mission yet, the Pimpernel must rescue a young man accused of being the Pimpernel - and discover whether Chauvelin was behind a plot to plant the false avenger in France.
