Iron Lung Movie: Plot and Setting
The story of “Iron Lung” is set in a post-apocalyptic universe, after an event called the “Quiet Rapture” wipes out all stars and habitable planets. Humanity’s last hope lies in a mysterious moon with a vast ocean of blood. A convict is sent on a solo mission to explore this moon using a tiny submarine called the Iron Lung. Trapped inside the submarine with no communication and only basic controls, the convict faces unknown dangers and psychological terror, making for a deeply claustrophobic and suspenseful experience.
