Zvijezde su nestale. Planeti su nestali. Samo su pojedinci na svemirskim stanicama ili svemirskim brodovima ostali da daju kraj nazivu – Tiho raspuštanje. Nakon desetljeća propadanja i rušenja infrastrukture, Gvožđa je otkrila na pustoj mjeseci AT-5 ocean krvi. Nadajući se otkriću nužnih resursa, odmah pokreću ekspediciju. Konstruira se podmornica i zatim se u nju privede zatvorenik. Zbog pritiska i dubine oceana, prednji pogled je obložen metalom. Ako uspiju, dobit će slobodu; ako ne, slijedi druga ekspedicija. Ovo će biti 13. ekspedicija.

Premise and Setting
Iron Lung opens on a bleak, post‑apocalyptic Earth where the Quiet Rapture has erased all stars and planets, leaving a few scattered space‑station survivors. The film follows Simon, a convicted criminal, as he is welded into the SM‑13 submarine—nicknamed the Iron Lung—and tasked with navigating the blood‑filled ocean of moon AT‑5 to retrieve a data‑black box that may save humanity. The setting is claustrophobic, with the sub’s sealed hull and limited oxygen adding palpable tension.
The Convict and the Submarine
Simon is a hardened convict whose past is shrouded in mystery, and his imprisonment on the submarine is both punishment and a chance for redemption. The sub’s cramped interior, its single porthole sealed in metal, and the reliance on an X‑ray camera to see beyond the hull force Simon to confront his fears. The crew’s voices through the intercom add an eerie psychological layer that drives the narrative.
The Quiet Rapture Explained
The Quiet Rapture is an event in the film’s lore where every star and planet vanished without warning, plunging humanity into isolation. It explains why only a handful of space‑stations survive and why the remaining humans are desperate to find resources. The disappearance creates a backdrop of existential dread that fuels the urgency of Simon’s mission and adds depth to the film’s bleak atmosphere.
The Blood Sea and Its Secrets
The ocean of blood on moon AT‑5 is a visceral, alien environment that challenges both physical and psychological limits. As Simon maps the sea, he encounters skeletal remains, mysterious creatures, and corrupted water that corrodes the sub’s systems. Audio logs from previous missions hint at a dark secret beneath the surface, but the film deliberately keeps many questions unanswered, heightening the sense of cosmic horror.
The Mission's Moral Weight
Simon’s task—to retrieve vital data and survive—raises questions about sacrifice and justice. He is offered freedom only if he completes a perilous journey that may lead to his death. Throughout the film, he must balance the responsibility to preserve humanity with his own desperate hope, creating a tense moral dilemma that propels his internal conflict.
Production and Design
The film’s low budget was offset by inventive practical effects, including over 80,000 gallons of fake blood that drenched the set. Markiplier’s self‑financing and hands‑on direction allowed a creative control that gave the movie an intimate feel. The claustrophobic set design and limited cast focused the tension on Simon’s experience, making the visual storytelling as much about atmosphere as plot.
Audience Reception
Iron Lung received mixed reviews, with critics noting its slow pace and lack of traditional scares. Nonetheless, it achieved impressive box‑office returns, buoyed by Markiplier’s massive YouTube following. Fans praised its atmospheric depth and the film’s ability to provoke discussion, while some viewers found its open‑ended narrative frustrating. Overall, it stands as a bold experiment in low‑budget, content‑creator‑driven filmmaking.
