A family of four-parents Mark and Julia Langley, and their two children, 16-year-old Claire and 10-year-old Ethan-vacation at a remote Airbnb cabin in Tennessee to escape digital distractions and reconnect.

What starts with strange noises and flickering lights escalates into possessions, time anomalies, and fractured realities.
