Secrets of War (2014)

Tuur and Lambert have always been inseparable, but the war is tightening its grip and threatening to tear their bond apart. Tuur’s father has secretly joined the resistance, and his older brother appears to be involved as well. Lambert’s family, however, has chosen to cooperate with the Germans. When a mysterious girl arrives from the city, she quickly befriends both boys—but shares a dangerous secret with only one of them. That decision drives a wedge between the friends and ultimately places her in grave peril.
