Merlin and Gaius suspect that Lady Carina is not quite as she seems after showing up in Camelot. Arthur isn't happy when his father flirts with her. When Merlin discovers that she is really a troll he finds it impossible to get Arthur to listen to him. Merlin tries to stop Catrina from ruining Uther's life but she has her eyes set on an even bigger prize.
Merlin is a young warlock who arrives in the kingdom of Camelot after his mother arranges for him to stay with the court physician, Gaius. He discovers that the king, Uther Pendragon, has outlawed magic and imprisoned the last great dragon deep under the kingdom.
The dragon tells Merlin that he plays an important role: to protect Uther's son, Arthur, who will bring forth a great kingdom. When Merlin meets Arthur, he believes that he is arrogant and Arthur, likewise, views Merlin as subservient. Merlin must keep his magic secret or face being executed by Uther.
