450,000 years ago, Great Britain was not an island, but a peninsula of mainland Europe. This documentary investigates the cataclysmic "Megaflood" that breached a massive limestone barrier between Dover and Calais, permanently altering the map. We explore the engineering of the Ice Age: how 3,000-meter-thick glaciers acted as conveyor belts, transporting Scandinavian rock to build the hills of Germany and Denmark.
