Season 2 of Orphan Black premiered on April 19, 2014 with 10 episodes on BBC America. The show's renewal was officially announced on May 2, 2013, halfway through the successful run of its first season.
Orphan Black, hits the ground running with Sarah in a desperate race to find her missing daughter Kira—a wild pursuit that brings her head-to-head with ruthless pro-clone, Rachel, Sarah's scorched earth tactics sparking a war, dividing and imperiling all the clones. This season also rejoins Sarah's clone sisters Alison and Cosima as they struggle to keep their clone world a secret and pick up the pieces of their broken lives - all while dealing with the harsh reality that no one around them can be trusted. As Sarah discovers more about her past, mysterious newcomers appear, but can they be trusted?
As the mysterious world of Orphan Black widens, new layers of the conspiracy are peeled back. Season one introduced Sarah, whose life changed dramatically after witnessing the suicide of a woman who looked just like her. Sarah learned that, not only were she and the woman clones, but there were others just like them, and dangerous factions at work set on capturing them all. She forged an alliance with fellow clones Alison Hendrix and Cosima Niehaus - and together they've been fighting for their freedom and the safety of their loved ones.
This season the trio's bond remains strong but they've all made choices that have dire consequences, leaving Sarah to navigate a dangerous world of new enemies and shifting allegiances. She immediately sets off fighting for survival and willing to risk everything to find her missing daughter Kira and foster mother, Mrs. S. Unsure who to trust, Sarah starts an all out war against immense forces. A powerful member of the Dyad group of companies, clone Rachel Duncan, has been tasked with negotiating the allegiance of Sarah and the other clones. She'll stop at nothing to complete her mission, using those who love Sarah as leverage, including confidant Paul Dierden. But Sarah is willing to risk everything and employs scorched earth tactics that inevitably imperil the clones.
Alison, in a fit of desperation to preserve her perfect suburban world, signed a deal with the Dyad Institute to maintain the life of a Stepford wife with husband Donnie and her children - but at what cost? The death of her friend Aynsley and the constant suspicion she's being watched are taking a toll on her sanity. Paralyzed by paranoia, she finds a shoulder to lean on in Sarah's feisty foster brother Felix, who after getting lost in the shuffle of Sarah's life, is happy to finally be needed. Cosima isn't faring any better. Sick with a mysterious illness and facing her mortality, the consequences are severe. Unfortunately, their enemies might be her only hope, and Cosima must work with Dyad Institute scientist and lover, Delphine, to find a cure before it's too late.
