n the quiet corners of the world, junkyard worker Ernie believes he’s just another ordinary man—until two mysterious strangers reveal a horrifying truth: he was never meant to be human at all. Deep beneath the earth lies a hidden civilization of Mandrills, a secret global militia fighting a monstrous cabal of billionaires known as the Lords of Brimstone, who traffic children and worship an ancient demon. As Ernie discovers his true form and joins the underground army, he learns that the world’s most powerful elites are hiding rituals, kidnappings, and unimaginable evil behind their wealth and influence. But when the Mandrill Militia launches a brutal assault on the cult’s secret gathering deep in the forests of California, the hunters become the hunted in a night of blood, revenge, and supernatural terror. The battle for humanity’s future will erupt in darkness, tunnels, and fire as ancient evil meets an unstoppable underground army. This year, the truth claws its way to the surface—because the creatures hiding below the earth may be the only ones standing between mankind… and hell itself.
