Around 1200 BC, nearly every major power around the eastern Mediterranean collapsed within about fifty years: palaces burned, cities emptied, and several writing systems vanished entirely. Egyptian inscriptions blame a coalition of raiders they called the Sea Peoples, and the film follows archaeologists testing whether any single force could have brought down the Hittite Empire, Mycenaean Greece, and Bronze Age Crete that fast. Krzysztof Nowicki climbs to the mountaintop refuges Cretans built when the coastline stopped being safe, reading fear directly out of where people chose to live. Clay tablets from the port city of Ugarit describe enemy ships offshore and a fleet that never returned home. The film also weighs alternatives to the invasion story: drought, earthquake swarms, and a trade network so interdependent that losing tin or copper shipments from one region could stall bronze production, and with it entire economies, everywhere at once. The collapse itself is not in dispute; the film's real subject is which combination of causes could break a connected world that fast.
