Ahead of tonight's Season 4 finale, BBC America has announced "Orphan Black" will return next year for a fifth and final season.

Ten episodes have been ordered, with Tatiana Maslany of course reprising her multiple roles in the sci-fi thriller as the members of the "clone club."

"'Orphan Black' is a thrilling, genre-bending ride that has captured our fans’ imaginations and hearts like no other show," Sarah Barnett, president of BBC America, said in a statement. "Our genius team of actors, writers and producers have, time after time, taken us to a place of awe, delight and utter shock and surprise. Tatiana has been and continues to be a complete revelation, hers is one of the most remarkable performances on television, and she is joined by an extraordinary cast. We can’t wait to take our incredibly passionate audience on one final gobsmacking clone adventure.”

Co-creators John Fawcett and Graeme Manson added, “We are excited to deliver an epic conclusion to the tale of Sarah and her clone sisters. The past four seasons have been a phenomenal adventure and we are eternally grateful to our loyal fans who have loved the twists and thrills of our weird little show."

The Season 4 finale airs tonight at 10 ET/PT on BBC America.
