1942, Amsterdam. The Nazi occupation has shattered the lives of inseparable best friends Hannie and Sonja. The canals and rainy cobbled streets they once strolled down are now patrolled by soldiers day and night, who arrest people at will and beat those who resist. Hannie can't stand by and watch the lives of the innocent be destroyed by the evil occupiers. At great danger to herself, she joins the underground resistance, where she meets the charming and mysterious Jan. She covers her bright red hair to avoid detection by the Nazis while distributing fake IDs. And she makes a promise to Sonja and her little sister Maya, who are Jewish - she will hide them and keep them safe, no matter the cost. But as the German grip on the country tightens with each passing day, Sonja's worst fears come true when members of her family are taken prisoner. With Jan by her side, Hannie goes undercover as a nurse to try to free them. But she's devastated when she discovers they've been taken to a concentration camp in the isolated far east of the country. Is she too late to save them?
