Former East Prussia. Sasha Zagorsky had been fascinated since childhood by the search for mythical underground tunnels of the Third Reich beneath Kaliningrad. This led him to personal tragedy and… to salvation in a global apocalypse.
The destructive blast wave reached Kaliningrad as well. There is no metro in this city, but there are bunkers with numerous tunnels built by the Germans during the height of the Second World War. These very underground passages saved several thousand people from total annihilation. Eighty-eight years after the war, followers of their ancestors' cause — Nazi legionnaires — came to claim what was theirs. The time has come to learn the secrets of the Third Reich's scientific discoveries.
