A two-hour special featuring a deserted Caribbean city, an American ghost town still burning, a Japanese no-go zone, an Arctic settlement facing a terrifying future, a sprawling Taiwanese facility that drew liquid gold down from the hills, and a once great lake that's now a barren desert.

A juggernaut of Soviet engineering which was crucial to the international space race. Deserted Scottish coastal defences, an complex that is a crucial part of American history and an ancient Greek settlement that was shaped by years of violence.
