Every week, Josh Gates, a world adventurer and eager truth-seeker, and his small crew of production buddies visit a different international destination alleged to be the home of a notorious, supernatural or mysterious creature, such as the Chilean Chupacabra, as well as some lesser-known phenomena, such as the dinosaur-like creatures reported in the skies over Papua New Guinea, a haunted village in Thailand and the wolfman of Argentina. Josh searches for evidence to either prove or debunk these stories by talking to witnesses and experts and immersing himself in the local culture.
