Discovery Channel Sets Special 'Expedition Unknown' Event About the Afterlife (Exclusive)

Discovery Channel has greenlighted a four-part special event of its series Expedition Unknown that will focus on the afterlife.

In Expedition Unknown: Search for the Afterlife, host and executive producer Josh Gates will travel the world to find scientific evidence of the afterlife and try to answer the question: Where do we go when we die?

Gates' journey begins in the ancient city of Hierapolis, Turkey, where he explores a recent archeological discovery: a portal to the underworld. According to ancient Roman accounts, something within this legendary cave killed every animal that stepped inside, and Gates investigates why.

Gates also visits India and Peru, where he sails down the Amazon River to a remote compound where shamans take him to the brink of the afterlife using ancient medicine. He also visits the jungles of Indonesia to find a village where the dead co-exist with the living.

Meanwhile, in the United States, he examines the spirit world through an expert psychic and takes part in a ghost hunt at one of the most haunted places on Earth.

The special event is set to debut Sunday, Oct. 7, at 10 p.m., followed by an aftershow, Expedition Unknown: After the Search, featuring never-before-seen footage and behind-the-scene moments, along with a discussion with Gates, at 11 p.m.

Expedition Unknown is produced for Discovery by Ping Pong Productions. For Ping Pong, executive producers are Brad Kuhlman, Casey Brumels and Gates and co-executive producers are Brea Tisdale and Matthew Meltzer. For Discovery, executive producers are Daniel A. Schwartz and Bill Howard and coordinating producer is Cameron Doyle.
