Based on a true story, the film is about a group of British miners (known as "Claykickers" or “Manchester Moles”) recruited during World War I to tunnel underneath no man's land and place mines below the German front for the Battle of Messines in 1917. The Germans reported 10,000 soldiers were killed instantly after the detonation of explosives beneath their lines.
