在这部碉堡剧情/战争片中,影片根据真实事件改编。二战期间，一群盟军战俘在挖掩体时，遇炮火袭击，在躲避时，意外地被埋葬在地下深处一个坚固的混凝土掩体内，虽然里面存放有足够的食物和蜡烛，足够这几人生存多年，但长时间的暗无天日的地下生活，使人意志逐渐崩溃...
During D-day several people become trapped while hiding in a bunker, when heavy shelling collapses it. They have plenty of food and water so they decide to wait for rescuers. And so they wait year, after year, after year.
