Josh Gates takes us beyond the grave in Discovery's four-part special event Expedition Unknown: Search for the Afterlife. Gates journeys across the globe to investigate into the spirit world and answer mankind's greatest unsolved mystery - where do we go when we die? From a ghost hunt at one of the most haunted places on earth to getting a firsthand glimpse of the afterlife with ancient medicine, Josh will put it all on the line for a glance of what's beyond this life. The show is followed at 11pm by Expedition Unknown: After the Search with never-before-seen footage and behind-the-scene moments.
