Horizon Zero Dawn, based on the PlayStation video game, is set a thousand years in the future, in a strange and beautiful world full of primitive tribes and high-tech machines, all built on the bones of the ‘Old Ones' – the ruins of our present-day United States. The disaster that destroyed our world is long forgotten, but when these formerly peaceful machines mysteriously turn into dangerous hunters of all life, a young outcast named Aloy discovers that the only chance to save her world is to fight to uncover what happened to ours.
