The adventures of ebullient handsome defender of justice Jean de Pardaillan in the Paris of 1588. The sprightly Gascon knight first saves a beauteous Bohemian girl, Violetta, from abduction but the young lady goes on being threatened by the henchmen of the evil Duke of Guise, for she is no gypsy at all but a young noblewoman, Isabelle d'Entraigues, heiress to the throne of France. What de Guise plans is to marry her, despite his relationship with princess Fausta, and become King himself. He has "Violetta" kidnapped again, successfully this time. Pardaillan swings into action, determined not to let faithless de Guise achieve his aims...—Guy Bellinger
