Markiplier stars in ‘Iron Lung’ – An Ocean of Blood

The Plot of Iron Lung

Lights out. In a post-apocalyptic world, all the stars and planets disappear in an event called “The Quiet Rapture.” The only people left live on spacecrafts, exploring abandoned, desolate moons. However, one moon sticks out like a sore thumb – it has an ocean of blood. One convict is chosen to explore this mysterious ocean in hopes of freedom. If he fails, more will follow.

That convict is none other than Mark Fischbach, AKA Markiplier, the famous YouTube actor and filmmaker. Markiplier writes, directs, produces, and stars in Iron Lung.
