In a post-apocalyptic future where an event known as "The Quiet Rapture" caused all known stars and habitable planets in the universe to disappear, a convict is sent to search an ocean of blood discovered on a desolate moon, using a small submarine nicknamed the "Iron Lung".

A claustrophobic video game adaptation that can veer into just plain stifling, Iron Lung is more interesting for its production than its story, but it conjures enough atmosphere to announce Mark Edward Fischbach as a filmmaker to watch.

A psychological descent that keeps hope out of reach, Iron Lung may be a slow burn, but its mood and atmosphere still leave a lasting scorch.
