Alan Gregory is a clinical psychologist with a thriving practice in Boulder, Colorado. His life begins to unravel when one of his female patients is found in an apparent suicide and the local paper begins printing accusations from an unnamed source of sexual impropriety between the woman and Dr. Gregory. He launches a psychological and personal quest for the truth that rapidly intensifies when more of his patients die untimely deaths, and Gregory suspects not only that the deaths are related but that another one of his patients may be somehow involved. Lacking facts but roused by suspicion and troubled by seemingly random acts of terror around him, Gregory starts to fear for the safety of the people he loves.
