Warren discovers in the tunnel some writing which he translates. He thinks the writing has something to do with quantum physics, but also discovers that freeing the girl also released her demonic aspect... just before the demon kills him. Now the demon is in pursuit of her human half, killing everyone that gets in her way.
Maria Ford plays Alyda Winthrop, and spends most of the film completely nude while clinging to Carter, fighting with other women, or trying to get frisky. She has to be coaxed into clothes, adding some humor to the film (which has several moments of levity). Julie Strain's ponderous breasts are also a featured part of her demonic costume, so for those who want some nudity with their gore there is plenty.
