The core premise follows submarine commanders Johannes von Reinhartz and Ulrich Wrangel in a cat-and-mouse pursuit across the Atlantic, alongside Klaus Hoffmann's survival in New York and Gestapo pursuits in La Rochelle—storylines rooted in period military and espionage conventions without modern ideological overlays. Prominent female characters Simone Strasser and Margot Bostal continue resistance work by aiding a Jewish family (the Goldblatts) in escape attempts, a plot point that aligns with documented historical resistance efforts rather than contemporary activism.

Season 1 introduced lesbian elements to Simone's arc with Carla Monroe, carried forward here through their political engagement, but these remain secondary to survival and anti-Nazi actions without lectures on identity or systemic issues. Casting features period-appropriate European and American actors in roles fitting the multinational setting, with no established character race- or gender-swaps.

German reception controversies focused on perceived historical revisionism via American profiteer subplots, not progressive messaging. No creator statements emphasize DEI mandates or norm-challenging intent.
