The Commandos Strike at Dawn

Erik Toresen (Paul Muni) is a mild-mannered widower who lives in a tranquil village on the coast of Norway. When Nazis occupy the area, however, the peaceful existence of Toresen and his neighbors is upended. Unwilling to tolerate German brutality, Toresen assembles a resistance movement and later discovers a secret Nazi military base. He then travels to England to inform Allied forces about the German location, and accompanies a group of commandos in an assault on the Nazis.
