The latest teaser for the upcoming third season of BBC America’s addicting sci-fi series Orphan Black packs a punch. Series star Tatiana Maslany reprises clones Cosima, Sarah, Helena, and Alison here and they warn of an impending war. The teaser also touts the surprising revelations made at the end of last season: that little girl there is Charlotte, the youngest Project Leda clone; the hooded male figure is Mark and the scarred one is Rudy, the two new male clones (played by Ari Millen) who stem from Project Castor.

For more insight into the new season, head over to EW where you’ll learn more directly from the source–series co-creator Graeme Manson.

Orphan Black returns April 18, 2015.
