At Dusk (2015)

Claudia is a young reporter who is forced to move to the small Southwestern mining town of Nemonto Hills, when her boyfriend, Sean, is transferred for his job. While on a camping trip to the nearby springs, they discover a camcorder with what appears to be the mysterious, grizzly murder of two hikers. As a reporter, she's compelled to investigate the case against the better judgment of her boyfriend. The two soon become unwittingly involved in a decades old conspiracy that has gripped the small mining town. When the sadistic man, the Regent, who runs the town, finds out they have the footage, it becomes a race to reveal or bury the truth forever. Claudia and Sean soon join forces with a rogue cop, and a retired sheriff who reveal to them that the footage is only the tip of the iceberg of a much more complex, sinister plot.
