A group of prisoners are sentenced to certain death by exiling them to the secluded Mount Grimrock for vile crimes they may or may not have committed. If they ever wish to see daylight again and reclaim their freedom the ragtag group of prisoners must form a team and descend through the mountain, level by level.
