Merlin would have been killed by a giant griffin (half eagle, half lion) if not for valiant Lancelot, who bravely attacked it and got them safely away. Learning Lancelot's life dream is to become a knight, grateful Merlin brings him to court, but when told only noblemen may apply, magically forges proof of nobility. Lancelot passes hazing and close combat tests against Prince Arthur but is found out as commoner and jailed. When the griffin attacks Camelot - even inside the royal castle - the knights' arms prove unable to penetrate it . Arthur frees Lancelot, who in return (with Merlin's magical help) triumphs where all knighthood fails miserably, but will Uther finally hear Arthur's plea to allow the best sword to serve in chivalry despite existing social restrictions?
