It is the time of the German occupation. Juliana's thoughts and actions are aimed at defeating the Germans. But the Princess also suffers personal problems. When she hears she and her children should go to Canada, she gets violently in conflict with Bernhard and Wilhelmina. She feels exiled and not taken seriously.
Juliana finally sees she has no other choice. She uses her time in Canada to convince Roosevelt and others to intervene in Europe. She also helps the Dutch, who stay in America during the war.
During her stay in Canada Juliana feels torn. First, she feels liberated from the strict court of Wilhelmina: she secretly enjoys the relative anonymity and fantasizes about a life as normal ma'am. Moreover she feels very guilty about this. She thinks it her duty to be queen, especially when her people are afflicted by the German occupiers. Moreover, she suspects infidelity of Bernhard. Suspicions that turn out right.
When she returns to the ruined Netherlands after the liberation and sees tired mother , she knows what to do: help with reconstruction and succeed her almost overwrought mother as soon as possible.
