Episode 1
Hitler's Forbidden Island (Guernsey)
Wed, Feb 25, 2026
Why would the Nazi's pour so many resources into this strategically insignificant island, and hold onto it at all costs even at the end of the war when the end was surely near? What dark secrets lie buried in the tunnels, bunkers and watchtowers dotting Guernsey?
Episode 2
The Devil's Lair (Maisy Batteries)
Wed, Feb 25, 2026
A mysterious map marked 'area of high resistance' leads military collector and historian Gary Sterne to an empty farming field not far from Omaha and Utah beaches. But there's nothing there - that is until Gary begins to dig and explore. Now, nearly seven decades after D Day, a massive Nazi artillery base, the size of four football fields, poses hard questions for WWII experts. Why did the Germans build this particular base is such secrecy? How did it continue to fire for three terrible days after the initial beach landings? And most importantly; why was it buried and lost to history? Was it perhaps meant to be forgotten?
Episode 3
Conspiracy on Death Island (Villa Winter)
Wed, Feb 25, 202642 mins
Officially retired German engineer Walter Winter built a remarkably secluded villa in an outskirt of Winter Fuerteventura, the second)-largest of the Canary Islands. Even its construction decade under Spain's Franco dictatorship is disputed. Its heir champions, but is forbidden by the local authorities to prove by digging the 'conspiracy theory' that it served as secret Nazi base, which fits some evidence, notably its extremely robust design, complete with military grade bunker, and -also wartime- observations from locals suggesting it may have involved forced labor and a torture chamber. The military purpose remains a mystery, as the alleged servicing of U-boot is unlikely given the rocky, tempestuous coast renders approach ludicrously dangerous, even if the conveniently located volcanic caves could have been used to dock in. Mysteries include the purpose of an oven hot enough to melt metals and an 'autopsy table', fitting the theory it was converted after the Nazi defeat became obvious for plastic surgery on those going in hiding to South America.
Episode 4
The Doomsday Castle (Kraftwerk Nord West)
Wed, Feb 25, 2026
The 'Blockhaus' (bunker) of Éperlecques, named after a forest near Watten, in northern France near the Channel but off the coast, was a Nazi super-bunker built under the code name Kraftwerk (power plant) Nord West. Its location didn't fit the Atlantic wall, yet Organisation Todt gave it extreme priority on Hitler's persistent orders, using almost unlimited building material and slave labor. The Alies utterly ignored its purpose, yet were convinced it was no decoy but worth bombing at all cost, so they did, and the Germans kept rebuilding, even inventing novel safer techniques to do so. Ultimately they abandoned the site except as an elaborate decoy for a similar, hidden bunker nearby. It was designed as launch and final construction site for the super-weapon V2, a state of the art guided missile which luckily for England came too late to crush it, and had been less easy to counter if Hitler had followed Arms Minister Speer's advise to use mobile launch platforms on rails instead.
Episode 5
Mystery Of The Nazi Nukes (Bergkristal)
Wed, Feb 25, 2026
A secret weapons program that could have ended badly for the allies. In the heart of Austria, a bunker and network of tunnels were discovered based on a long lost 1944 German report that indicated what the Nazis were up to. The government says the radiation in the hills is natural, but a team of experts say differently. How did this site go undiscovered for so long after the war? Was it meant to be forgotten? What experiments and advances were the Germans working on in these secret tunnels?

The Germans have fled 5 days earlier, taking or destroying as much documentation and equipment as they can. As the Soviets investigate the tunnels and bunkers, curiously carved and built into the forest landscape, to guarantee absolute secrecy, they realize the terrible materials manufactured in Dag Bromberg. How did the Germans keep this colossal base secret from allied intelligence? And what technology and secrets did the base give up behind the iron curtain after the war?
