We meet Will (Ben Foster) and his 13-year old daughter Tom (Thomasin McKenzie) as they are camping in a park near Portland, Oregon. They are both clearly comfortable in the woods, and also with each other. They forage for food, make campfires, and practice drills to keep out of sight of prying eyes. As viewers, we soon figure out that they are not on a camping trip – this is in fact where and how they live.
