In a post apocalyptic world, holiday treasures disappear: Fireworks factories erupt, Christmas tree farms grow out of control; real reindeer must adapt or die. Vacation icons fall, from high-end resorts and cruise ships, to roller coaster thrill ride. A Holiday Hell ensues.

What if every human being on earth disappeared? This isn't the story of how we might vanish--it is the story of what happens to the world we leave behind. In this episode, we'll see what happens to some of the bodies left behind. Most embalmed and buried, some mummified, others cryogenically frozen. Will any of them truly achieve immortality? Or will they be outlived by other memorials to mankind, like the Statue of Liberty or the Sistine Chapel. This is just part of a journey that will take us to the future of cities of Boston and Houston--as well as haunting sites already devoid of man. CC HD [TVPG]
