BBC America has renewed its acclaimed sci-fi drama "Orphan Black" for a fourth season.

Created by John Fawcett and Graeme Manson, the series stars Tatiana Maslany in multiple roles, as clones created as part of a scientific movement, but raised separately and spread across North America and Europe. In the third season, which concludes June 20, the militaristic male clones of Project Castor come to the forefront, posing a deadly threat.

"’Orphan Black’ is an entirely fresh and original show that stands out even in today’s crowded TV landscape," Sarah Barnett, president and general manager of BBC America, said in a statement. Tatiana Maslany’s buzzy, virtuoso performance headlines a brilliant cast and we are delighted to let our vocal and passionate fan base know that this wildly entertaining ride will continue next year.”

Airing Saturdays at 9 p.m. ET/PT, "Orphan Black" also stars Ari Millen, Jordan Gavaris, Dylan Bruce, Maria Doyle Kennedy, Skyler Wexler, Kevin Hanchard, Evelyne Brochu, Kristian Bruun, Ksenia Solo, Michiel Huisman, Josh Vokey, Zoé De Grand Maison, Justin Chatwin and Kyra Harper.
