Travis stops at a cafeteria and requests direction to the institution to the waitress Jill. Her troublemaker brother Nate has a friction with Travis but Sheriff Billnick resolves the case and gives a ride to Travis to the institution. He brings Lloyd home and he explains that New Purgatory is cursed and trapped in a loop every three years, when the monster comes back with new abilities and kills residents, until Lloyd destroys it.
