About this season
Journalist and writer Graham Hancock travels the globe hunting for evidence of mysterious, lost civilizations dating back to the last Ice Age. He attempts to prove that a climatic event 12,000 years ago wiped out an entire civilization far more sophisticated than the simple hunter-gatherers some archaeologists believe lived at that time.
