Adventures of Thierry de Janville, nicknamed "Thierry la fronde or Thierry the sling-slingshot", after his weapon of choice. A young of brave nobleman in XIVth century France, Thierry and his (merry ?) men fight oppression, by thwarting every bad deed of the evil Black Prince - the son of the king of England - whose armies are occupying the Aquitaine region. Together they restore hope (mainly by saving Isabelle, Thierry's love interest, from the claws of the English in every other episode) in the hearts of the french people.
