History is made one brave act at a time. Henny has grown up with her father’s boat, the Gerda III, as a home away from home. She loves sailing the waters between Denmark and Sweden, carried along by the salt breeze. But when Nazi rule tightens in Copenhagen, Henny joins the resistance. And when Hitler orders the Gestapo to round up all Jewish citizens, Henny realizes that the Gerda III isn’t just a boat—it’s a means of escape for her Jewish neighbours. Safety and freedom are just across the channel in Sweden—as long as Henny doesn’t get caught.
