The clones are all played by Maslany in an incredible Emmy Award-winning performance. Not knowing who created them or why, the identical "sestras" forge deep bonds with each other. As this unusual family unravels the insidious conspiracy behind the clone experiment, the sisters place themselves at great risk to attain freedom for themselves, their families, and the host of clones they have yet to meet.
