Following its successful debut on BBC America, BBC Three has released a new trailer for Orphan Black, a ten-part thriller starring Tatiana Maslany (The Nativity, Picture Day).

Maslany plays Sarah Manning, an outsider and orphan whose life changes dramatically after witnessing the suicide of a woman who looks exactly like her. Sarah assumes her identity, her boyfriend and her bank account. But instead of this solving her problems, the street-smart chameleon is thrust headlong into a kaleidoscopic mystery. Sarah quickly finds herself caught in the middle of a deadly conspiracy and must race to find answers about who her doppelganger really is…

Orphan Black also stars Jordan Gavaris (Degrassi) as Sarah’s foster brother Felix; Dylan Bruce (As The World Turns) as Paul, Beth’s boyfriend and Maria Doyle Kennedy (Downton Abbey) as Mrs S, Sarah’s foster mother.
