In the final days of World War II, time seems to have stood still in a hidden concentration camp deep within the forest. Prisoners of war, serving as ruthless test subjects for inhumane experiments, struggle to survive behind the iron bars of a dark laboratory. Directed by Sergio Garrone, this film delves into the most unsettling corners of the war genre. Amid the electric hums echoing off the camp’s cold walls and in this realm where depravity has become the norm, the quest to perfect the Aryan race is pursued with maddening obstinacy. Drifting through the dark waters of horror cinema, the film leaves the viewer stranded in the middle of a tunnel with no way out.
