What will happen once human cloning becomes scientifically feasible?
That question is addressed with chilling logic in BBC America's superb sci-fi thriller Orphan Black, which returns for a second season Saturday at 9 p.m. And it ain't pretty.
Tatiana Maslany plays multiple roles as clones - we've met seven so far - created by a powerful conglomerate named Dyad and its scary head scientist, Aldous Leekie (Matt Frewer).
Set in Toronto, Orphan Black is told principally through the eyes of one of the clones, English-born grifter and single mother Sarah Manning.
The story opened last season as a fascinating mystery. At loose ends for money, Sarah one day witnesses an identical-looking woman, police detective Beth Childs, commit suicide. Intending only to empty her bank accounts, Sarah grabs Beth's wallet and keys and assumes her identity. She soon finds herself enmeshed in a deadly conspiracy.
