In the aftermath of a devastating bio-chemical conflict that has obliterated 99% of the planet, technology has become irrelevant, and the land is so contaminated that food is scarce. The remaining humans struggle to survive by hunting and eating the undead. However, this leads to horrifying consequences as the dead flesh, still affected by the lingering bio-chemicals, starts to mutate. As a result, people’s digestive systems evolve in a bizarre manner, forcing their way out of their mouths to independently seek nourishment. These mutations escalate wildly, culminating in a grotesque climax.
