A section of the National Resistance, led by Andreas, plans an act of sabotage against the occupiers. Martha offers valuable assistance in achieving their goals, thanks to her relationship with an SS officer. The first phase of the sabotage involves stealing documents from Nazi headquarters. The mission is successful, but the Germans' retaliation is terrible. They discover, arrest, and execute all members of the resistance group. They kill Martha and Fritz. Andreas leaves to continue the resistance in the Middle East.
