During World War I, a group of soldiers find themselves trapped in a small, claustrophobic bunker, cut off from the rest of the world. As they wait for rescue, they begin to experience strange and inexplicable occurrences, including eerie sounds and shadows that seem to move on their own. As time passes, tensions rise and paranoia sets in, with each man becoming increasingly suspicious of his fellow soldiers. The unrelenting fear and terror of their situation begins to take a toll on the men, driving them to the brink of insanity as they struggle to survive the horrors of war and the malevolent force that seems to be working against them.—Frank Liesenborgs
