A mysterious place, an indescribable prison, a deep hole. An unknown number of levels. Two inmates living on each level. A descending platform containing food for all of them. An inhuman fight for survival, but also an opportunity for solidarity.

During an exclusive tour, a power breakdown inside a secret prison known as the Death House sends two agents fighting through a labyrinth of horrors while being pursued by a ruthless army of roaming inmates. As they fight to escape, the agents push toward the lowest depths of the facility where they learn a supernatural group of evil beings is their only chance for survival.
