The Addisons -- Julia and Tonio, ten-year-old Dewey, and derelict Uncle Robbie -- are driving home, cross-country, after collecting Robbie from yet another trip to rehab. When a terrifying blizzard strikes outside the town of Good Night, Idaho, they seek refuge in the town at the Travelers Rest, a formerly opulent but now crumbling and eerie hotel where the physical laws of the universe are bent.
