In Expedition X, Josh Gates joined by scientist Phil Torres and paranormal researcher Heather Amaro to investigate reports of supernatural encounters, mysterious creatures, and astonishing extraterrestrial phenomena. Whether trekking through the remote jungles of Cambodia in search of a legendary ape-man or exploring the secrets of the world's largest cave system right here in the United States, the Expedition X team is taking viewers to the stranger side of the unknown.

Making her debut in Expedition X Season 8 is third-generation paranormal investigator Heather Amaro. Amaro notably replaced former host Jessica Chobot, who was one of the main stars of Expedition X for its first seven seasons.
