It is the 1930s. A global crisis is spreading, and growing discontent gives rise to new radical movements such as fascism. This ideology is gaining ground not only in Germany but also in the Netherlands, and society becomes divided as a result. Boxing friends Ben Bril and Sam Olij find themselves diametrically opposed during these years.

The German Reich under the leadership of Adolf Hitler is growing at a terrifying rate. One by one, countries are falling prey to his ruthless expansion. It is May 10, 1940, when the Netherlands is attacked and Dutch soldiers must face a superior German force. Meanwhile, Commander-in-Chief Winkelman must try to keep a cool head.

The Netherlands is occupied by Nazi Germany. The Nazis regard the Dutch as a brother nation and emphasize that they will treat them with respect. At least... if the Dutch comply. German soldiers are billeted in families' homes, leading to tensions in Dutch living rooms.
