Die Brücke.

A group of German boys are ordered to protect a small bridge in their home village during the waning months of the second world war. Truckloads of defeated, cynical Wehrmacht soldiers flee the approaching American troops, but the boys, full of enthusiasm for the "blood and honor" Nazi ideology, stay to defend the useless bridge. The film is based on a West German anti-war novel of the same name, written by Gregor Dorfmeister.
