The psychotic behavior of a set of twins, Jennifer (Shirley Parker) and June Gibbons (Sharon Parker) is the focus of this disturbing true story. While still quite young, the twins vow never to speak to anyone except each other -- though their own relationship is clearly either abusive or conspiratorial. Various vignettes underscore their abnormality, making anyone wonder why they were not given the psychiatric treatment they so obviously needed. In the end, it took a drastic and tragic action on their part before the public sat up and noticed they were desperately in need of therapy.
