In this episode of Haunted Highway, Jael and Devin hit the road to Idaho and arrive in the abandoned town of Silver City. This Old Western ghost town has been plagued with rumors of multiple ghostly visitations. Crisscrossed by dangerous underground mines and featuring a hotel where many have died tragically, this place is called a "ghost town" for a reason! A tense night investigation reveals paranormal activity on a scale Devin and Jael are shocked to discover, and an EVP session conducted by Jael in a hidden isolation chamber leads to a terrifying climax to the investigation. The team then heads out to rural Montana on the search for a ferocious cryptid predator that has been stalking the prairies for centuries.

Described as a fast, giant wolf-like creature, Jael and Devin have to exercise caution as they track the beast on its own territory. They decide that the best plan is try to lure the monster with live bait, but on the night investigation they begin to wonder whether they are the hunters or the prey!
