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.

Zak, Nick and Aaron showcase the locations where they have performed spiritual rituals, resulting in their most intense moments. Through séances, libations and voodoo practices, the guys open the gates to the spirit world and summon the voices of the past, resulting in a powerful connection to lost souls. When the guys dare an entity to show its face, the spirits prove to be unforgiving.
