November 1941, the Protectorate of Bohemia and Moravia. Under Reinhard Heydrich, the Nazis establish the Theresienstadt Ghetto in Terezín. Nearby, the Small Fortress becomes a prison run by the Gestapo.

Its commandant, Heinrich Jöckel, rules through fear. Prisoners—including resistance members, civilians, and prisoners of war (captured soldiers)—face starvation, disease, and relentless brutality inside the overcrowded fortress.

Between 1940 and 1945, over 32,000 people were imprisoned there, with thousands losing their lives under harsh conditions.

As Nazi Germany collapses, Jöckel attempts to escape justice—but his story does not end there.
