Rebecca Warfield and her husband Ben McCormick are investigating out of body experiences by subjecting monkeys to electric impulses. They see it as pure science, but to religious groups such as Family Foremost, it is a sacrilege. Desperate for funding, Rebecca decides to run the experiment with a human subject — herself. She asks her assistant, Amy, to help. But Amy, a secret religious fanatic, alters the experiment. Rebecca escapes from her body, but, unless she finds a way to communicate, she will remain trapped in another dimension.
