What would happen if, tomorrow, every single person on Earth simply disappeared? Not dead, just gone. In this documentary, nature is finally given the chance to take the world back. But how would that work? How long would our skyscrapers and homes last if we abandoned them? How would our animals and pets fare without us? How much of human civilization  will last as long as the pyramids? This is a world you will never see – a world without humans.
