Aimee and Alan have unusual pasts and secrets they prefer to keep hidden. Aimee's deceased mother struggled with mental illness and hallucinations, and Aimee thinks it could be hereditary. After all, she sees a shadowy river man where there isn't one. And then there was that time she and her best friend Courtney tried to conjure a spirit with a Ouija board … Alan is Courtney's cousin. His family moved to Maine when Courtney's father went missing. It's not just Alan's dark good looks that make him attractive. He is also totally in touch with a kind of spiritual mysticism from his Native American heritage. And it's not long before Aimee has broken up with her boyfriend … But it's not Aimee or Alan who is truly haunted – it's Courtney. In a desperate plea to find her father, Courtney invites a demonic presence into her life. Together, Aimee and Alan must exorcise the ghost, before it devours Courtney – and everything around her.
