When World War II begins, Max Brekendorf, a proud young German naval officer, fights for his country with honor and courage. With the unstoppable German war machine overrunning Europe, Max looks ahead to a bright future with his fiancée, Mareth. But as the war progresses, their future together becomes less and less certain. German victories begin to fade. In the North Atlantic, Max must face the increasing strength of the Allies on ever more harrowing missions. Berlin itself is savaged by bombing, making life for Mareth increasingly dangerous and desperate. And as the Third Reich steadily crumbles, Nazi loyalists begin to infiltrate Max's crew and turn their terror on Germany's own armed forces. Recognizing what his nation has become, Max is forced to make a choice between his own sense of morality, and his duty to the Reich.
