Profecía diabólica (El poder de Satanás) (1978)
Un matrimonio, ambos médicos, compra un caserón abandonado desde hace tiempo con el fin de convertirlo en una clínica de rehabilitación de drogadictos. Pero no cuentan con que esté encantado. Cuando allí se trasladan junto a un grupo de voluntarios y amigos para rehabilitar la casa, en una noche de tormenta, comenzarán a percibir la voluntad que habita el lugar.
