An extreme adventure tour group headed by deep caving expert John Palmer descends into a 2000 Ft abandoned salt mine , that was mysteriously closed down years ago after an unexplained disaster trapped all of the miners . They prepare for rock slides , blackouts , cave-ins - whatever might threaten their journey and commence their descent into the depths.
A descent into suffocating darkness where the earth itself seems to conspire against you. Expect primal fear, gnarly practical effects, and a relentless sense of being trapped with something ancient and hungry.
