Tuurs dad joined the resistance and even his big brother seems to be a part of it. Lamberts family on the other hand choose to obey the Germans. Then a new girl from the city shows up, befriending the boys but telling her secret to only one of them. A choice that separates the boys and ultimately gets her in trouble.
