The Addisons - Julia and Tonio, ten-year-old Dewey, and Uncle Robbie - are driving home after collecting Robbie from yet another trip to rehab. When a terrifying blizzard strikes outside the town of Good Night, Idaho, they seek refuge at the Travelers Rest, a formerly opulent but now crumbling hotel.
With nowhere else to go, they decide to stay the night. But once inside, the family becomes separated and the hotel begins to work its eerie magic. As Julia and Tonio drift through the maze of the hotel's spectral interiors, Dewey ventures outside. Meanwhile, a desperate Robbie quickly succumbs to his old vices. As they desperately try to reach each other, they relive the same day over and over again. The mother, Julia, holds the key to their release - but can she save her family from the fate of becoming Souvenirs - those citizens trapped forever in Good Night - or, worse, from disappearing entirely?
