Part 1: Secret Cities of the A Bomb
In 1939, a group of scientists--Albert Einstein among them--warned FDR of the possibility that Hitler's Germany might be close to producing an atomic bomb. Roosevelt issued an order--the U.S. had to do it first. It was the most costly and labor-intensive engineering program ever undertaken, but within three years they were well on their way to creating a hidden world of secret cities and classified nuclear facilities. Six decades later, Lost Worlds returns to the places where history was made, visiting three top-secret cities in isolated parts of Tennessee, New Mexico, and Washington State. Using classified material, eyewitness testimony, and cutting-edge graphic technology, we recreate the secret world of the Manhattan Project.

Part 3: Churchills Secret Bunkers
During WWII, a vast complex of secret bunkers was constructed under the streets of London. It was a vital refuge from the nightly onslaught of Nazi air raids, and only recently has its full extent been revealed. The existence of Churchill's Bunker is no secret, but the fact that there was an entire subterranean city built to keep the British government running is only now being revealed. Very little of this covert network, which also sheltered American General Dwight Eisenhower, has ever been revealed to the public. Now this lost world is brought back to life--the tunnels beneath the heart of London's great buildings; the underground command center from where the Battle of Britain was coordinated; the ultra-secure chambers that could withstand the most deadly weapons in the Nazi arsenal. Beneath the streets of London, Lost worlds expose wartime secrets we were never meant to know.
