Warchild (2006)

Senada, a young mother whose only daughter Aida was removed from Bosnia-Herzegovina during the worst years of the war and presumably adopted into a Western European family. Searching for her after the war, Senada enters illegally into Germany, where she discovers through a social worker the harsh truth of postwar adoption: Aida is alive and well and living happily with a German family. Dark secrets emerge, leaving no one unscathed.
