Colette and Alison are unlikely cohorts: one a shy, drab beanpole of an assistant, the other a charismatic, corpulent psychic whose connection to the spiritual world torments her. When they meet at a fair, Alison invites Colette at once to join her on the road as her personal assistant and companion. Troubles spiral out of control when the pair moves to a suburban wasteland in what was once the English countryside. It is not long before the place beyond black threatens to uproot their lives forever.
