When her aunt steps off a grain elevator into the emptiness of a prairie evening, Mira Piper loses her one protector. Chloe, her flighty mother, impulsively drags her daughter to Bramblewood, an isolated spiritualist retreat in northern Michigan, run by the enigmatic Dr. Virgil Simon. Chloe plans to train as a medium but it's Mira who discovers she can communicate with the dead. When her mother abandons her, Mira discovers a darker aspect to Bramblewood: the seemingly kind doctor has a sinister side and a strange control over his students. Then one winter's day Troy Farrington arrives, to fulfill his mother's dying wish and deliver her letter to the doctor. But calamity strikes and he finds himself a captive, tended by a sympathetic Mira. Haunted by her dead aunt and desperate to escape Bramblewood, Mira makes a devil's deal with Dr. Simon. But fulfillment comes with a steep cost...betrayal.
