Lancelot lives by the sword. In fact, they're next door neighbours, so teaming up to fight for money comes pretty naturally. Lady Guinevere, on her way to marry King Arthur is ambushed by the evil Sir Malagant. Fortunately Lancelot is lurking nearby and he rescues his future queen. They fall in love, but Guinevere still fancies the idea of wearing a crown, so she honours her promise to Arthur. Can Lady Guinevere remain faithful, or will this Pretty Woman become a lady of the knight?
Merlin, Excalibur and all things supernatural are out of this picture, as King Arthur, aged and war-weary is forced to go to battle one last time against the traitor Prince Malagant, whilst in the meantime his new bride Guinevere and new knight Sir Lancelot betray the king in their own way.
