When promising young psychiatrist James Richardson is offered the job opportunity of a lifetime by Dr. Hugh Maitland, he is thrilled. His task is to manage a controversial therapy in which disturbed patients are kept asleep for months. But Richardson begins to sense something uncanny about the patients. Why is Maitland unwilling to discuss their past lives? Why is the trainee nurse so on edge when she spends nights alone with them? And what can it mean when all the sleepers start dreaming at the same time? Richardson finds himself questioning everything he knows as he attempts to uncover the shocking secrets of the sleep room.
