The Grey Zones

In October 1944, a small, tightly knit group of Sonderkommando prisoners at Auschwitz‑Birkenau clings to a dangerous plan: to mount an insurrection that would destroy at least one of the camp’s crematoria and its gas chambers. Their courage is fueled by hidden supply lines—firearms provided by Polish villagers and gunpowder smuggled from the nearby UNIO munitions factory. The women who work at UNIO become crucial couriers, slipping powder through the camp amid the bodies of their dead colleagues. When the German guards finally uncover the women’s covert activity, they are subjected to brutal torture, but the plot remains stubbornly intact, its secrets held tight by those who would rather die than betray their comrades.

At the heart of the story stands Dr. Miklós Nyiszli, a Hungarian‑Jewish doctor who works in an experimental medical lab under the Nazi doctor Josef Mengele. Dr. Nyiszli, Rubén Darío Gómez Arias, has been granted permission to visit his wife and daughter in the women’s labor camp, a concession that comes with a paranoid fear for their safety. He clings to a line of hope: Mengele’s orders might spare his family from the gas chambers—at least, for now—even as the world around him becomes a trap of moral compromises and mortal danger. His wife is the figure the men in the camp call Mamá, and she is portrayed by Carmen Emilia Porras Uribe. The fragile hope Nyiszli clutches is tempered by the ever‑present threat of discovery and reprisal.

A fresh trainload of Hungarian Jewish prisoners is brought to the camp and sent toward the gas chambers under the pretext of a routine delousing. Tension tightens the air as a fearful man in the group shouts questions at Hoffmann, one of the Sonderkommando. The confrontation escalates quickly; Hoffmann’s impulsive violence ends a life, and the consequences ripple through the ranks. After the gassing, Hoffmann discovers a girl alive beneath a pile of corpses. He extracts her and hides her in a storage room, summoning Nyiszli to revive the child. The insurgents decide to hide the girl in the children’s camp, a decision made with quiet resolve despite the ever‑present danger. The girl’s presence becomes a beacon, a fragile thread of humanity amid the machinery of death.

But danger intensifies when SS‑Oberscharführer Eric Muhsfeldt enters the scene. He notices that Abramowics—an inmate who is present illegally—is in the room and shoots him, the girl’s scream tipping off the guards to the hidden plot. Nyiszli steps outside and speaks with Muhsfeldt about the uprising, though he cannot reveal its timing or precise plans. Muhsfeldt makes a stark, troubling promise: he will protect the girl after the uprising is crushed, a pledge that casts a long shadow over every subsequent decision.

The uprising erupts in full force. Crematorium IV is destroyed with the explosives the group managed to smuggle in, and the surviving Sonderkommando fighters hold their ground through the brutal heat of fire and gunfire. Those who survive the initial assault are captured and later shot once the flames die down. Hoffmann and Rosenthal, another fellow prisoner, face the grim reality that the young girl they saved will not be spared after she’s forced to witness the executions. After the captives are executed, the girl is allowed to flee toward the camp’s main gate, but Muhsfeldt raises his pistol and ends her life before she can escape, a stark reminder of the brutal calculus that governed every choice inside the camp.

The film closes with a haunting, reflective voice‑over spoken by the dead girl and a stark on‑screen note about the aftermath: Muhsfeldt would be hanged for war crimes after the Auschwitz trials, while Nyiszli survived the war but never practiced medicine again. The narrative leaves the audience with a sober meditation on memory, guilt, and the fragile flame of humanity that persists even in the darkest corners of history.
