Deep in the mountains of rural Oregon, something sinister lies within. Despite the warnings from local residents about haunted hills, this doesn't stop mine owner Larry Overman on his hunt for gold. Welcome to sleepy Sumpter, a former boomtown tucked in the peaks of the Elkhorn Mountain Range. Larry is the newest owner of the Crescent Mine, an eighty-year old abandoned mine rumored to be still chock full of that shiny, valuable gold… and possibly the spirits of some of its long-dead miners.

One miner runs away; the team use a robotic probe and makes an eerie discovery in the mine.

Mysterious power failures in the mine leave one of the paranormal investigators shaken; and Kristen turns to a Native American historian for help as she tries to figure out what's going on.

Two miners claim to have experienced something paranormal while working in the mine, which leaves them feeling frightened. After hearing their story, Patrick and Kristen encounter a mysterious "phantom wind", which leaves proof to the miners claim.

Patrick and Kristen make a discovery about the mine that leads them to believe there is a secret passage to another tunnel, which they set out to find.

The miners vote to begin work in the new shaft, despite concerns raised by Kristen and Patrick, who fear an evil presence is lurking inside the old tunnel.
