Zak, Nick and Aaron rent an RV and drive through the night to reach the remote town of Rawlins, WY, to investigate one of their darkest haunts to date: The Wyoming Frontier Prison. From 1901-1981, Wyoming's first state penitentiary served as a virtual death house for as many as 200 inmates. While some of these deaths were the result of state-sanctioned executions, others died from harsh living conditions and the infamously brutal violence that took place behind its cold walls.

Zak, Nick and Aaron travel internationally to explore some of the world's most sinister haunts. From Jamaica to Italy, England to Canada, they've investigated the paranormal across the globe. Above ground, underground, in forts and on islands, restless spirits greet them in the most terrifying ways. The guys came in contact with foreign souls who were, for better or worse, aching to be heard. They visit a notorious Jamaican plantation, a haunted island that has been declared off-limits by the Italian government and underground caves where an English secret society was rumored to participate in pagan worship.
