Merlin: Season 1, Episode 7

1 - 7: The Gates of Avalon

Morgana has a dream that Arthur is murdered by a beautiful girl and warns him of it, but Arthur's chivalry lands him in trouble when he jumps to the rescue of a damsel in distress, Sophia, and her elderly father Aulfric. Back in Camelot, Sophia uses more than just her feminine charms to take control of Arthur's heart. This strange behaviour doesn't go unnoticed by Merlin, and he sets out to try to prevent a tragedy.
