At the war's end in Europe, Dietrich reunited with her sister Elisabeth and her sister's husband and son. They had resided in the German city of Belsen throughout the war years, running a cinema frequented by Nazi officers and officials who oversaw the Bergen-Belsen concentration camp. Dietrich's mother remained in Berlin during the war; her husband moved to a ranch in the San Fernando Valley of California. Dietrich vouched for her sister and her sister's husband, sheltering them from possible prosecution as Nazi collaborators. Dietrich would later omit the existence of her sister and her sister's son from all accounts of her life, completely disowning them and claiming to be an only child.
