In 1992, Jonah Greely was hit and killed by Molly McNamara and her husband David on Highway 41 in Nevada. His wife was so distraught that she killed herself. Each year on the anniversary of his death, Jonah finds another car driver to kill.
While Sam, Dean and Molly McNamara are driving down Highway 41, Greely appears in the middle of the road with his guts hanging out. Dean presses down on the accelerator and hits Greely, who quickly dissipates.
While out looking for Greely's grave, Molly hears a voice calling her name. Believing it to be her husband David, she begins looking for the source. Greely soon appears from out of nowhere and grabs Molly, before he can do anything Dean shoots him with rock salt. The three soon find Greely's home, and after searching inside find the corpse of Greely's widow hanging in the attic. After cutting her down and giving her a proper burial they return to the house.
Inside the house, the song "The House of the Rising Son" by The Animals begins playing, when Dean goes to investigate the source, he sees a window begin to frost over with the message "She's Mine" written across it. In another room, Jonah crashes through a window and grabs Molly and takes her back to his hunting cabin where he begins to torture her. After looking at a photo of Greely and his wife at their hunting cabin, Sam realizes planting a tree was used as old country markers for graves. Dean soon arrives at the hunting cabin and shoots Greely with rock salt, causing him to temporarily dissipate. Greely reappears behind Dean, but before Dean can act, Greely uses telekinesis to throw Dean across the room. Calling a hunting knife to him, he attempts to stab Dean. Meanwhile, outside Sam finds Greely's grave and salts and burns the corpse, finally laying him to rest.
