Doctor Strange and Wong return for a new adventure. The demon, Sattanish, has been unleashed by Baron Mordo to destroy Dr. Strange. In return for Mordo's action, Sattanish gives him unspeakable power, and he becomes an overlord of evil. Sattanish sees he is being manipulated by Mordo, and Sattanish drains his power and kills Baron Mordo. In the end, Strange and Wong must destroy Sattanish. After the ending credits, Eternity will be shown as he says "Oh no, is this another great evil I'm sensing?" leaving a cliff-hanger.
