PLOT
The Boy Merlin is a Thames Television fantasy show from 1979, starring Ian Rowlands in the title role, about the magician Merlin. Set in Wales during the Dark Ages, the series tells the story of the young apprentice magician Merlin — the grandson of King Conaan, fostered by the family of Dafydd Ismena. Merlin's father is unknown; some say he was a demon of the night. His foster-grandmother, Myfanwy, who also possesses magical powers, is the only one to realise that Merlin's destiny lies at the court of King Arthur, and it is she who schools him in magic and witchcraft. However, because of the circumstances surrounding his birth, Merlin is in constant danger from Vortigern, the Saxon High King, and his beautiful queen Rowena.
