When Germany surrendered in 1945, Europe held hundreds of thousands of children with no parents to claim them, separated by bombing raids, forced labor deportations, ethnic cleansing, and mass killings. This film tracks how postwar authorities and relief agencies tried to sort these lost children into national categories, and how some were quietly absorbed into new families as part of programs built around ideas of racial or national fitness rather than kinship. Archival footage of refugee camps, displaced-persons registries, and Red Cross tracing efforts sits alongside interviews and historical documents that reconstruct individual cases: children moved across borders, renamed, and in some instances raised without ever learning their origins. The film treats this as an underexamined continuation of Nazi-era population policy carried out after the regime that started it had already collapsed. Rather than a single sweeping narrative, it assembles a set of case histories that together show how the machinery of selection and relocation outlived the war itself, leaving a generation of adults today still searching archives for who they were before 1945.
