After a long and bloody war, Uther Pendragon begs the wizard Merlin to help him seduce the wife of his new ally, the Duke of Cornwall. Merlin agrees, but on the condition that the fruit of their union be given to him. That same night, Arthur is conceived. Eighteen years later, the nobles of a kingdom whose throne is vacant attempt to seize Excalibur, the magical sword that has been encased in stone since Uther’s death.
