In 17th-century France, Baron Philippe de Sigognac lives a modest life in his crumbling castle, the last scion of a noble lineage fallen into disrepair.

Despite the challenges of the road and the dangers they face, including skirmishes with highwaymen and the loss of one of their actors, Sigognac decides to join the troupe on their journey to Paris.

Renaming himself "Captain Fracasse" and taking on a role in their performances, Sigognac finds himself increasingly enamored with Isabelle, who reciprocates his feelings.

Despite Vallombreuse's interference and the challenges they face, including attempts on Sigognac's life and Isabelle's abduction, the troupe perseveres.

Eventually, it is revealed that Isabelle is the daughter of the Prince of Moussy, and her true noble heritage removes the obstacles to her union with Sigognac.
