An amazing discovery has been made beneath a farm field in Northern France: a vast underground city where World War I soldiers, on both sides of the conflict, took refuge a century ago. Even more remarkable, it is one of hundreds of buried havens set up close to a 45-mile stretch of the Western Front. Follow American explorer and photographer Jeff Gusky as he documents one of these long forgotten shelters, and witness his attempts to connect the names of the American soldiers etched into the limestone walls to their living descendants. 　　译文(3): 在法国北部的一片农田下，人们发现了一个惊人的发现：一个世纪前，冲突双方的第一次世界大战士兵都在这座巨大的地下城市避难。更引人注目的是，它是在西线45英里范围内建立的数百个被掩埋的避难所之一。跟随美国探险家兼摄影师杰夫·古斯基记录这些被遗忘已久的避难所之一，见证他试图将刻在石灰岩墙上的美国士兵的名字与他们在世的后代联系起来。
