(from BBC America's press release, May 2017) The fate of the clone sisterhood will be revealed when the final trip of BBC AMERICA's award-winning series, Orphan Black, starring Emmy(R)-winner Tatiana Maslany, returns Saturday, June 10th at 10/9c. From the moment Sarah Manning (Tatiana Maslany) locked eyes with an unknown identical woman, who jumped to her death - her life has never been the same. She's found out she's a clone, that there are multiple clones out there, and multiple factions that sought to hunt, control, betray or kill them. Now, the final showdown with Rachel (Maslany), the one clone at the center of it all who's sought to destroy her and her sestras from day one begins. And as the walls close in on her, Sarah must decide her next move very carefully, for this time, it's life or death for everyone she loves. When we last saw Sarah, she'd been badly beaten in an epic physical battle against Rachel, that left her bruised and broken. Her foster mum, Mrs. S (Maria Doyle Kennedy), and daughter Kira (Skyler Wexler) were taken hostage and her sestra Cosima (Maslany) went missing. Now, Cosima and Alison (Maslany), and their allies have been brought to heel. Even more harrowing is that Kira has joined them in surrender. Rachel, sitting at the head of the Neolution table, has carte blanche access to their clone biology, and with Helena (Maslany) pregnant with twins, her biology is the most coveted of all. Sarah in a desperate attempt to regain control, realizes she must change tactics to pursue a long game. She, and those still able to fight, will uncover the missing pieces of the insidious conspiracy - and finally free themselves from the tyranny that has taken over their lives. Despite the great risk, the fight of her life will either set her and her sestras free, or see them meet their end.
