An astounding exposé that gives voice to the unwitting subjects of an infamous American scientific experiment: the 1960s Neubauer-Bernard study of separated twins. Told from the perspective of the Jewish identical twins and triplets who were secretly split up in infancy and adopted through Louise Wise Services, a Jewish adoption agency, the documentary examines the traumatic, long-term effects of the separations — and continuing deception — on the children and their adoptive families.
