A passionate community, devoted to the world's greatest monster myth, is disrupted when an ambitious scientist begins the final, definitive search for the Loch Ness Monster. 36km long and twice as deep as the North Sea, Loch Ness is the custodian of the world's greatest monster myth. Leading the latest scientific quest is Professor Neil Gemmell, a Nessie-sceptic. He travels from New Zealand to Loch Ness in the hopes of showcasing his cutting-edge Environmental-DNA method on the world stage. With the help of an eclectic team of scientists, Neil begins a biodiversity study of the loch to determine what organisms live below the surface. Billing the expedition as 'the final, definitive search', Neil could soon be able to declare - once and for all - that there is no monster in Loch Ness.
