The Loch Ness Monster

S1, E5: Is believing in the Loch Ness Monster's existence really so outlandish? Kangaroos, giant squids, and even tigers were once considered mythical creatures.

It's possible something foreign to us could be hiding in the Scottish lake's cold depths, but is it probable? A detailed study exposes the truth behind the phenomenon, and investigates 80 years of photographs, videos, and thousands of eyewitness accounts.
