When a flesh-warping disease ravages a remote village in Mexico, a scientific task force travels to the inhospitable area to investigate the contamination. As victims of the illness are transformed in horrible ways, the task force traces the source of the disease to a nearby cave system. Venturing into the dangerous tunnels, the team discovers a bizarre, hostile ecosystem and a supernatural revelation from which they may never escape. Nothing can prepare you for the ghastly twists and turns of this completely different horror story. This new subterranean nightmare is brought to you by writers CULLEN BUNN (REGRESSION) and KYLE STRAHM (SPREAD) and rising star artist BALDEMAR RIVAS!
