In 1871, Aaron McCallum sees his wife, Anna, secretly meet a magician named Delgatto in the forest. When Aaron kills Anna with a knife by mistake, Delgatto places a curse on him to exist for eternity like an animal, killing in order to remain alive. In 1955, a former waitress named Lenore St. Clair drives the Interstate highway. In the woods, Aaron McCallum kills, and devours a wild deer, then returns to a cabin, where his elderly daughter, Hester, helps him to bed. Later, Hester casts a spell that causes Lenore to have visions as she drives, in which she sees Anna alone in the woods but believes she herself is the person in the vision. She shakes herself awake and picks up Cam Rollins, a hitchhiker. However, the two travelers quarrel, and Cam asks to be let out of the car. As Cam walks away, he sees her car tires stuck in the dirt. She orders him to help, and when he frees her car, she drives off without thanking him. However, she turns the car around, and offers him a ride for the second time, and apologizes for her poor behavior. Back at the cabin, as Hester drains blood from Aaron’s finger with a knife, Lenore has another vision, and nearly causes an accident. She tells Cam she is fine, but her hand has a gash similar to the one on Anna’s hand. Lenore describes being pulled into a forest, where a man injures her. When Cam suggests she see a doctor, she is upset. While Hester chants, Lenore’s driving once again becomes erratic. Hester slashes her own hand to offer her blood, and pleads with dark forces to take her soul. She carries a potion in a glowing decanter toward the fireplace. When the glow passes over her body, she drops the vessel. Meanwhile, Cam fears that Lenore will cause an accident, and orders her to stop the car. She crashes through several barriers and stops at the edge of a forest. Lenore tells Cam she cannot remember anything, and he suggests they walk back to the main highway. However, Lenore ignores him, heads toward the forest and he follows. Hester tells Aaron that instead of trading her soul for Lenore’s, a third person is now involved. Although Aaron is upset, Hester reminds him the curse will be lifted when he wakes in the morning. Aaron decides to visit Anna’s grave with a bouquet of flowers. In the forest, Lenore describes two men in her vision fighting over someone who is her double. Cam comforts her and they kiss. When she calls him Aaron, he becomes angry and shakes her. She hugs him tightly, then wanders away. She comes to a clearing, and sees two gravestones. Aaron appears and calls her “Anna.” Before, Lenore can respond, Cam arrives, explains they are stranded, and asks if they can use Aaron’s telephone. He has no phone, and invites them to stay the night at his cabin. Lenore advises Cam that Aaron is the man she saw in her vision. At the cabin, Hester is startled by Lenore, and believes she is the reincarnation of Anna’s spirit, then offers to dress the wound on her hand. Before she can finish, however, Lenore admires a glass sculpture Aaron made for his wife. He takes Cam to the attic to see others he has made. As Hester bandages Lenore’s hand, she stares intensely at Lenore because of her resemblance to Anna, her dead mother. Moments later, as Lenore admires Aaron’s glass sculptures in the attic, she asks Aaron and Hester whom they think she resembles. Hester offers a locket with a photograph of her mother, Anna, and Lenore exclaims, “It’s me.” However, Aaron explains that it is Anna, his deceased wife. Then Aaron shows a portrait of himself with his daughter, Hester. Lenore is not frightened that Hester has aged while Aaron remains young. She is intrigued and wants to know the family’s story. Aaron explains when his family first moved to the mountain, Delgatto fell in love with Anna. As the men fought, Anna was killed, and Delgatto’s revenge was to place a curse. According to Hester, the doors of hell will open and demons will emerge to claim, Lenore, as their prize. Then, Aaron’s spell will be broken. Cam is anxious, and persuades Lenore to leave in an antique Ford sedan they borrow from Aaron. As Hester predicted, demons appear on Earth. When their sedan hits something, Cam stops the car to investigate. He sees a dead demon, returns to the car and continues their journey. Meanwhile, other demons break into the cabin, destroying Aaron’s glass sculptures. Hester slips on broken glass, and is impaled by a protruding object. Soon, a demon attacks Lenore when they reach the spot where she abandoned her car. Cam overpowers the evil spirit, and it retreats. He grabs a tire iron from the trunk of Lenore’s car and they continue their escape on foot. At the cabin, Aaron apologizes to his daughter for all the pain. With her last dying breath, she assures him he is not at fault, and when the door to hell closes, he will be free from the curse. In the forest, Cam becomes separated from Lenore. Afterward, Lenore follows a voice in the night, calling for Anna. Lenore reaches Anna’s tombstone, but walks past it toward a door bathed in light. She disappears through it, and sees Delgatto on the other side. He kisses her. She recognizes Delgatto from her visions but insists she is not Anna. He disagrees and wants her love. Cam and Aaron arrive at Anna’s grave simultaneously. Aaron steps inside the glowing door to save Lenore and Cam follows. Soon, Aaron declares Delgatto will not steal Anna from him again. The men reenact their original fight. This time, Aaron kills Delgatto with the knife instead of Anna. However, Cam appears and ushers Lenore toward the door. At the doorway, Aaron reemerges and kisses Lenore, but Delgatto attempts to pull her into the underworld. Cam saves her, while Delgatto drops dead onto the forest floor of the mortal world. Nearby, Aaron is freed from his curse, but the price is death. His body withers, turns to dust, and the wind carries off his spirit. Arm in arm, Cam and Lenore walk out of the forest.
