Journalist Graham Hancock travels the globe hunting for evidence of mysterious, lost civilizations dating back to the last Ice Age


The show, narrated by author Graham Hancock, theorises that an advanced civilisation was all but wiped out by catastrophic climate change and floods around 12,800 years ago. Mr Hancock suggests this 'ancient apocalypse' was caused by a series of comet strikes that triggered a 1,000 year long mini ice age - a period known as the Younger Dryas.
