Three dwarven miners are trapped inside a mountain when a nearby tunnel collapses. The dwarves are unclear if help will arrive to save them in time given their lack of supplies. As they seek to survive long enough for rescue, the group soon learns that they are not alone in the cave whose deeper bowels house an aggressive creature. As they seek out supplies and protect themselves from the creature, they must fight feelings of hopelessness and despair that no one might actually be coming to save them.
