Europe 1990, the Berlin wall has just crumbled: Katrine, raised in East Germany, but now living in Norway for the last 20 years, is a “war child”; the result of a love relationship between a Norwegian woman and a German occupation soldier during World War II. She enjoys a happy family life with her mother, her husband, daughter and granddaughter. But when a lawyer asks her and her mother to witness in a trial against the Norwegian state on behalf of the war children, she resists. Gradually, a web of concealments and secrets is unveiled, until Katrine is finally stripped of everything, and her loved ones are forced to take a stand: What carries more weight, the life they have lived together, or the lie it is based on?
