The classics of French literature adapted to a non francophone public. One Ascension day, King Arthur gives a celebration in his castle. During the meal, Méléagant arrives and challenges him : Arthur must leave queen Guenièvre in his care and if any of Arthur's knights doesn't succeed in beating him, the queen will be kidnapped. Otherwise, the queen will come back as well as all the kingdom inhabitants that are prisoners in his land. Seneschal Keu accepts the challenge, but fails and the queen disappears with the terrible Méléagant. Only one man seems to be able to take her back safe and sound : Lancelot.
