Just days ago, Elizabeth Derby (Heather Graham) was a successful psychiatrist with a loving husband and the world at her fingertips. Now, she finds herself locked up inside a psych ward after the murder of a young male patient to whom she had an inexplicable, almost otherworldly attraction. Hoping to clear her name, Elizabeth confides in her doctor and recounts what happened, giving way to a bizarre and disturbing tale of sexual madness, supernatural horror, and homicidal rage. The deeper the story goes, the more unhinged and carnage-laden life becomes, not just for Elizabeth but for everyone in her path.
