YellowBrickRoad proposes that, in the 40’s, all the inhabitants of a small town just took off on a path into the mountains and disappeared. The records of the incident have been classified for whatever reason, and JUST NOW at the start of the movie, they’ve become available, and are claimed by a small crew hoping to follow the path and write a book on what they find.
…Can you reason out what may or may not be going on? Sure. But the film doesn’t ask you do that until the end, which makes me feel like no one really knew where they were taking the film until the end…
