 In 1918 in World War I, in the Meuse-Argonne Sector in France, the former New York lawyer and Major Charles White Whittlesey is assigned by Gen. Robert Alexander to a massive suicidal attack against the German forces in the Argonne Forest with his five hundred men battalion. However, the forces supposed to be giving support through the flanks retreat and the communications with the headquarter of the 77th American Division are cut. Major Wittlesey holds his position with his men, mostly Irish, Polish, Italian and Jew gangsters from New York, surrounded by the German army. Without food, water, ammunition and medical supplies, only two hundred men survive after five days of siege.
