Examine the apocalyptic fate of every home in the world. Gas leaks turn suburbs into infernos; a famous castle is toppled by a hidden flaw. Paint causes some high-end homes to explode in flames. Houses fall from the world tallest apartments to the most crowded complexes.

Massive waves of destruction threaten everything left behind by mankind in a post-apocalyptic world; U.S. cities face flooding as levees fail; famous paintings meet a tragic fate; a unique roof feature of the Sydney Opera House leads to its collapse

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]
