He calls his parents June (Sissy Spacek) and retired sheriff Chet (Kris Kristofferson) to say he'll be home for Thanksgiving. He confronts his former coach in Detroit, demanding money owed him. The two get into a fight and Jay, thinking he has killed him, flees, fearing he will be sent back to jail.Hannah (Kate Mara), the sheriff's deputy, visits Jay's parents, who invite her to join them for Thanksgiving dinner. At the police station, she is treated poorly by her father, sheriff Becker (Treat Williams), who does not want to include her in the hunt for the unknown criminals. Hannah, who has been accepted to be trained to become an FBI agent, excuses her father's behavior because of the loss of his wife, even though it was years ago.Jay finds a shivering Liza in the road and offers her a ride to the nearest gas station. Meanwhile, wandering in the snow, Addison encounters an elderly man tending to his damaged snowmobile. He attacks the man, who slices off Addison's little finger before being stabbed to death by his own knife. Addison drives off on the snowmobile, which he later abandons after it breaks down, but not before cauterizing his wound on the still hot engine.Jay and Liza stop at a bar during the blizzard. She sneaks back to his truck, finds Jay's address and leaves Addison a message to meet up there.

After dumping the man's body, he tends to the distraught wife and her children. Hannah is called by a woman concerned for her relative (the mother living in the cabin), not having heard from her, and promises to investigate.Realizing that she has feelings for Jay, Liza calls Addison to say she couldn't proceed with the plan and that she'll find another ride. Jay confesses his feelings for her. Liza explains how her brother was her protector from their abusive father, who was killed when they were young.Hannah and two officers reach the cabin.

She goes to the house and is also taken captive by Addison.Becker finds Addison's snowmobile at the house, draws a weapon and goes inside. He fires at Addison, but it turns out to be his daughter, Hannah, surreptitiously dressed by Addison in his own jacket. Becker is then shot by Addison. A struggle between Jay and Addison ensues outside. Jay overpowers Addison but releases him when Liza begs him to, reminding Jay that Addison is her brother.
