Iron Lung

2026 125 min ★ 7.3 Horror, Mystery, Science Fiction

The stars are gone. The planets have disappeared. Only individuals aboard space stations or starships were left to give the end a name -- The Quiet Rapture. After decades of decay and crumbling infrastructure, the Consolidation of Iron has made a discovery on a barren moon designated AT-5. An ocean of blood. Hoping to discover desperately needed resources they immediately launch an expedition. A submarine is crafted and a convict is welded inside. Due to the pressure and depth of the ocean the forward viewport has been encased in metal. If successful, they will earn their freedom. If not, another will follow. This will be the 13th expedition.

This time, it’s a “quiet rapture” that has caused mankind’s latest apocalypse, and so for the next couple of hours we spend time with a convict (Mark Fischbach) submersed in a vast and deep ocean of blood.
