75 years after D-Day, Philip Freriks travels after the protagonists of Operation Overlord.

On June 6, 1944, nearly 4 million soldiers on the Allied side and 1.4 million on the German side face each other. The D-Day invasion is the result of years of preparation. Freriks retraces the road of the soldiers in each episode and unravels what happened in the run-up to that one day.
