The 8th Plague

Launa is obsessed with investigating the disappearance of her sister who has not returned from a recent camping trip in the mountain town of Halcyon Springs. The search leads to an abandoned prison where Launa and her friends are exposed to an ancient evil that the stone walls of Halcyon Ridge can no longer hold back. Relentless terror, gore, and bone-chilling thrills are unleashed on anyone whose soul is exposed to this demonic curse. (official distributor synopsis)
