In the remote woods of Oregon sits Crescent Mine, one of America's richest gold mines. But the site had been forgotten after being abandoned decades ago when a series of tragedies gave it a reputation for being haunted. New owner Larry Overman has reopened the mine and hired a group of miners -- a mixture of veterans and rookies -- in hope of finding the mine's fortune. He is also tackling the haunted reputation head-on by teaming his miners with paranormal investigators Kristen Luman and Patrick Doyle. The latter are tasked with unraveling the location's mysteries, including historic Masonic connections and a spirit known to haunt the area for generations, while the miners face the day-to-day challenges that come with the job.
