She knows it's all a game and so is disturbed when images begin to appear in her crystal ball. Her visions begin to come true and soon the students begin to believe she is a witch and threaten her. Sarah has dreams about the Salem witch trials and feels she is re-living them. The threats grow and she realises that her life is in danger. As the story seems to be moving to a shocking climax, Sarah's mother and her friend intervene and prevent disaster.
