Berlin, 1940. Otto and Anna Quangel write dangerous postcards, distributing them to houses across the city. They want to rouse and warn the Germans: Hitler has been in power for too long, and war would mean the end of Germany. The couple risk their lives with this tiny act of resistance. Will Kommissar Escherich find out who’s behind the postcards? Who can help him? And who’s helping the Quangels?
