Circle Of Fear - S1.E2

Dai tells Matt to come to his home, ""The Sanctuary,"" if he ever needs help. Adam discovers that there is an underground rock dish beneath the village with the stones at its perimeter. Matt suggests that psychic lines emanating from the stones delineate an inner circle surrounding Hendrick's manor house. Later that night, he finds the villagers forming a ring around the manor house and chanting. When he tries to get closer, Dai grabs him and throws him against a stone.
