Children of the Stones - Season 1 Episode 3 Serpent In The Circle

Matt awakens back at the cottage and tries to tell his father what happened to him, but Adam thinks his son was just sleepwalking. At school, Jimmo has become very good at mathematics and has obviously joined ""The Happy Ones."" Dai explains to Matt that he was protecting him from the stones the night before. He suggests that the circle within the stones is a maze with the treasure of knowledge at its center. Dai is protected from the stones' power by an amulet with a serpent on it. In the meantime, Adam is told by Hendrick that the stones align in space with a black hole, which he discovered--Hendrick's Supernova.
