If you’ve ever watched a World War I movie and thought, “This is good, but what if the trench trauma came with cosmic horror, demon goo, and a radio that absolutely cannot be trusted?” then Bunker is very much your cursed cup of tea.
Adrian Langley’s 2022 horror-thriller takes the classic “war is hell” premise and adds, “Also there is an eldritch HR department down here feeding on your despair.” It’s claustrophobic, grimy, weird as hell, occasionally bonkers—and honestly, that’s its charm. This is what happens if 1917 got locked in a room with Event Horizon and a stack of Lovecraft paperbacks.
Welcome to War, Here’s Your Doom Basement
We start with Lieutenant Turner and his tired, muddy, definitely-not-fine battalion: British soldiers Miller, Lewis, Walker, Hall, and young American recruit Baker, plus medic Private Segura. It’s WWI, so everything is wet, loud, and emotionally broken. An officer shows up to check on “morale,” which, as in most wars, is code for “please lie to me so I can write a nice report.” Turner obliges, because acknowledging that everyone is falling apart is bad for one’s promotion prospects.
Then the opposing German camp suddenly goes quiet. No lights, no shells, no “we’re still here trying to kill you” energy. Turner decides this is obviously good news and not, say, the opening scene of a horror movie. He orders an advance across no man’s land, where the mud is thick, the bodies are mutilated, and the audience is quietly yelling, “Turn. Around.”
Naturally, they do not.
The Bunker: Do Not Open, No Really, Don’t
The men cross the corpse-strewn battlefield and find the German trench, which looks like a war crime and a haunted house had a baby. Among the carnage they find a door that’s been sealed from the outside—the international sign for “whatever’s inside is worse than what’s outside.”
Naturally, they open it.
Inside is the bunker: dark, cramped, clearly used, and very wrong. They find a lone German survivor, Kurt, crucified in a way that screams “ritual sacrifice” more than “standard POW procedure.” Before they can fully process that, shelling hits, the bunker collapses, gas rolls in, and suddenly a routine horror mistake (“we shouldn’t have gone in there”) becomes a survival situation. Turner, Baker, Segura, Walker, Lewis, and Kurt manage to stay alive by donning gas masks conveniently left by the previous occupants who, frankly, should have left a note that said “WE TRIED TO WARN YOU.”
And now they’re trapped underground with:
-
Limited food (which will get worse, don’t worry),
-
A crucified German who is probably not just a guy,
-
A radio with “bad idea” energy,
-
And a rapidly deteriorating grip on reality.
So, a normal WWI deployment, plus demon.
War Is Hell, But Also the Hell Is Hell
Once the men are stranded in the bunker, the film leans hard into psychological horror. Segura, the medic, emerges as the closest thing we have to a sane person: he patches wounds, tries to keep the peace, and cautiously befriends Kurt, like a man who suspects the crucified German might be a problem but also realizes he’s the only one not actively losing his mind yet.
Lewis spends his time on the radio, desperately calling for rescue and getting increasingly weird responses. It starts as static and vague orders and gradually morphs into something that sounds like motivational cult propaganda filtered through a cathedral. Before long, he develops religious delusions—ranting about being chosen, interpreting nonsense as divine guidance. It’s like the radio is slowly tuning his brain to “prophet of madness FM.”
Walker, already wounded, starts self-mutilating in a trance. Not the cute kind of trance, either. If you’ve ever wanted a visual metaphor for the way war eats its own, watching a soldier cut up his own body as if something inside is trying to claw its way out is… effective.
Turner, the lieutenant, doubles down on control. As conditions worsen, so does his need to stay in charge. He becomes more erratic, more paranoid, and more violent—a perfect vessel for the entity lurking in the bunker. It’s a reassuring message: even in supernatural horror, middle management will ruin everything.
The Angel of War: HR Department of the Abyss
Kurt, once revived and untied, reveals that he is essentially a walking sacrifice—“the lamb”—for a creature he calls “The Angel of War.” This is not the peaceful, harp-playing variety of angel. This one feeds on despair and violence, and has picked a fantastic venue: an underground bunker in WWI. It’s like opening a Starbucks in the middle of a conference; the foot traffic is built in.
The radio, we realize, isn’t receiving commands from Allied HQ. It’s the entity whispering, manipulating, keeping the soldiers disoriented and in conflict so it can gorge itself. The more they fight, the more they suffer, the tastier the buffet. If you’ve ever suspected that some wars exist purely to feed something ugly and inhuman in the background, congratulations: this movie agrees with you, and then gives that ugliness tentacles.
The “rations” in the bunker? When they crack open the cans, they’re not full of beans. They’re full of the same viscera and white slime that Walker vomited up. The horror here isn’t just biological; it’s spiritual contamination. Even the food has been converted into a sacrament of corruption. Bon appétit.
Violence, Fragmentation, and One Very Unhelpful Grenade
As the entity’s influence spreads, the group spirals.
-
Lewis, now full-on zealot, attacks Turner while holding a grenade. In the struggle, he dies and Baker’s hand is mangled.
-
Turner becomes more obviously possessed—command devolving into tyranny.
-
Segura and Baker cling to sanity and to each other, trying to dig upward with Kurt’s help, hoping there’s a way out that doesn’t end in madness or bodily explosion.
It’s a nicely structured descent into chaos: each man succumbs in a different way—violence, delusion, self-harm, authoritarian control. The bunker isn’t just a place; it’s a pressure cooker for their psyches. The Angel doesn’t have to do much; it just nudges. Humans provide the rest.
Segura: Reluctant Hero in a World That Does Not Reward Therapy
Eddie Ramos’ Segura is the closest the film has to a moral center: a medic, a rational observer, and one of the only men still asking, “Should we… not do this?” as everyone else happily dives into spiritual quicksand.
He’s the one who realizes the radio isn’t their salvation, but their jailer. He’s the one who sees Kurt not just as “the enemy” or “the sacrifice,” but as someone trapped in the same nightmare. And, eventually, he’s the one who understands that no one is coming to rescue them from this thing. The cavalry is not on the way. Sometimes, the only way to stop a monster is to pull the roof down on both of you.
Segura kills Turner when the lieutenant becomes fully corrupted—an act of mercy for the squad, if not for Segura’s conscience. He manages a brief victory: escaping the bunker, getting Baker to Allied medics topside. For a flicker of time, you think, “…Oh. Maybe he actually gets out of this.”
Then he goes back for Kurt.
Of course he does.
Go Back for the German, Blow Up the Demon
When Segura returns to the bunker to free Kurt, the Angel finally drops the subtle act. It erupts from Kurt’s wound in a grotesque display and drags Segura into a vision—a hallucinated purgatory of violence, guilt, and war. It’s not just trying to kill him; it’s trying to convert him.
But Segura, bless his doomed heart, chooses self-sacrifice instead. He blows the place—himself and the entity included—sealing the Angel of War back into the earth with rubble, fire, and enough symbolism to power a film studies class.
War created this thing. War fed it. And ultimately, a soldier who was supposed to just patch people up ends up being the one to slam the door on it. It’s tragic, heroic, and appropriately messy.
Mud, Madness, and Surprisingly Sharp Teeth
Bunker isn’t a huge-budget, glossy horror epic. You can feel the constraints: a tight set, a small cast, and a lot of moody lighting doing heavy lifting. But that works in its favor. The bunker feels oppressive because it is oppressive. There’s nowhere for these characters to hide, from each other or themselves.
The film’s great strength is how it uses war as both setting and metaphor without ever going, “By the way, have you noticed war is bad?” It trusts you to connect that a creature called the Angel of War, feeding on human misery, is not actually that far off from reality—just less subtle.
Is it perfect? No. Sometimes the pacing wobbles, sometimes the goo outperforms the dialogue, and occasionally you’ll want to shake a character and yell, “Stop listening to the creepy radio voice; this has literally never gone well in any medium.”
But it’s atmospheric, ambitious, and unexpectedly heartfelt beneath all the slime and shrapnel. It takes a familiar message—war destroys everything—and adds, “Yes, and sometimes, if we’re not careful, it makes something that likes it that way.”
If you’re into claustrophobic horror, dysfunctional soldiers, and the idea that Hell might just be a bunker with no exit and terrible rations, Bunker is absolutely worth descending into. Just… if you ever find a sealed door on a battlefield, maybe don’t open it. Let some other movie deal with that.
