Shookum Hills (2021)

A group of young geologists hire a desperate female guide to take them to a mysterious mining town that had a fire many years ago and is no longer marked on maps. After being lost, the company asks the locals for directions, but they advise to get out of the way and even start chasing the intruders. Despite this, geologists still find a hidden path in the forest and an abandoned city surrounded by an energized fence, and inside the perimeter there are strange holes in the ground.
