Season 1

August 1944. In Nazi-occupied Saint-Malo, Marie broadcasts through an air raid — an act punishable by death. Werner, a young German soldier, listens in.

During an intense interrogation, Marie recalls the Nazi invasion of Paris as Werner remembers a fateful visit from an SS officer to his orphanage.

After earning Etienne's trust, Werner opens up about his haunting past and his ties to shortwave 13.10. Daniel goes to great lengths to trick the Gestapo.

A hellbent von Rumpel makes his final bid to find the Sea of Flames. As artillery falls and American forces breach the city, Werner races to save Marie.
