Sarah Manning (Tatiana Maslany) and her fellow clones Beth Childs, Katja Obinger, Alison Hendrix, Cosima Niehaus, Helena and Rachel Duncan (all played by Tatiana Maslany) search for answers in the new trailer for Season 2 of Orphan Black, which debuts Saturday, April 19 at 9 PM ET with "Nature Under Constraint and Vexed". The last trailer that debuted in March revealed that Sarah is still searching for her missing daughter Kira (Skyler Wexler). This footage, set to the Yeah Yeah Yeahs' song "Gold Lion," reveals that until Sarah and the others come back to heal, Rachel will withhold treatment for Cosima, who continues to suffer from a respiratory illness. Take a look at these new scenes before the hit series returns on BBC America later this month.
