Plot

Uther Pendragon (Gabriel Byrne) is in battle against the Duke of Cornwall (Corin Redgrave), and reminds Merlin (Nicol Williamson) of his promise of the "Sword of Power", Excalibur to denote his kingship. Merlin retrieves the sword from the Lady of the Lake (Telsche Boorman) and gives it to Uther to unite the land. After Uther yields portions of "lands from here to the sea" Cornwall yields to Uther. Cornwall invites Uther to celebrate at his castle, where Uther meets and is enchanted by Cornwall's wife Igrayne. Cornwall is enraged and the truce is broken. The lustful Uther later lays siege to the Duke's castle.
