Merlin - Season 1 Episode 1

Young Merlin, sent by his mother from their village to start a better life, arrives in Camelot where he is to be apprenticed to Gaius, physician to the repressive King Uther. Uther, believing all magic evil, has made it punishable by death, so when Gaius finds that Merlin has magical, telekinetic powers, he agrees to keep the boy's secret. The mother of a sorcerer Uther recently executed comes to Camelot for revenge in the guise of a pretty girl, charming the court to sleep with her singing. Only Merlin sees what is happening and, staying awake, saves the situation without exposing himself as a warlock. As a reward, he is promoted to valet of Uther's arrogant son, Arthur.
