Catherine Deane is a beautiful young therapist who has mastered the radical technique of neurological synaptic transfer. To demonstrate her unique skills, Deane successfully communicates with a young boy in a coma by entering his mind on a subconscious level. When FBI Agent Peter Novak hears of her skills, he recruits her to help him crack open the savage mind of a serial killer who, after suffering a seizure, has also fallen into a coma. However, time is short. While Deane traverses the nightmarish mind of the killer, the clock ticks down for his latest victim -- a woman who is entombed in in a demonic plexiglass cell designed as a torture chamber that will eventually fill with water.
