The Devil Below is a 2021 horror film that was directed by Bradley Parker.
A group of scientists, led by an adventurer named Arianne, have been searching for the lost mining town of Shookum Hills. The town hasn't been placed on maps since the 1970s, its population of 1000+ having disappeared alongside Shookum Hills. It's believed that the disappearance is related to rumors of underground fires that resulted in sinkholes swallowing up the town and team leader Darren believes that the fires were started by a rare mineral.
