Orphan Black verteld het verhaal van een vrouw die er achter komt dat er meer mensen op haar lijken, en dat zij en de anderen een kloon zijn. De onderstaande trailer ziet er heel erg goed uit, en de serie zelf begint vanaf 30 maart.

Sarah hopes that cleaning out a dead woman's bank account will solve all her problems. Instead, her problems multiply - and so does she. Experience a whole new side of BBC AMERICA with the channel's next original scripted series, "Orphan Black," the exciting and ambitious new addition to the Supernatural Saturday programming block. "Orphan Black" features rising star Tatiana Maslany "(Cas & Dylan," "Picture Day") in the lead role of Sarah, an outsider and orphan whose life changes dramatically after witnessing the suicide of a woman who looks just like her. Sarah assumes her identity, her boyfriend and her bank account. But instead of solving her problems, the street smart chameleon is thrust headlong into a kaleidoscopic mystery. She makes the dizzying discovery that she and the dead woman are clones... but are they the only ones? Sarah quickly finds herself caught in the middle of a deadly conspiracy and must race to find answers about who she is and how many others there are just like her.
