The show stars Tatiana Maslany as Sarah, a young woman who encounters a complete stranger who looks just like her moments before the stranger kills herself. Sarah assumes the stranger's identity to escape from her own life, but realizes the freaky coincidence is only the beginning of a deeper, darker mystery.

BBC America will air "Orphan Black" under its Supernatural Saturday banner with all new episodes of "Doctor Who" as its lead-in. Chris Hardwick's "The Nerdist" will round out the night.
