Howard Bell thought he hit rock bottom the day he returned to his former employer with a loaded gun. Instead of putting a scare into his ex-boss as he intended, things quickly get out of hand, and he kills five people. Howard is sentenced to life at an experimental prison camp off the coast of Antarctica, and he soon learns the true definition of "rock bottom." Prison life at the remote island involves back-breaking work in the illegal mine run by the corrupt warden and his abusive guards. After a mysterious object is discovered deep in the mine, the inmates and staff start dying from an unknown infection. Howard is lucky to find himself one of the few survivors immune to the pathogen, but he and his fellow inmates learn something far more sinister and terrifying also has emerged from the mine. The truly lucky ones are already dead.
