'Orphan Black' Season 3 Trailer: The Clones Are In Danger (VIDEO)

It looks like Sarah (Tatiana Maslany) and her clone sisters have even more to be fearful of in Season 3 of "Orphan Black."

Rudy (Ari Millen) and the male Castor clones seem to be causing major trouble for Dyad, and as a result, the very lives of Cosima, Helena, Alison and Sarah are hanging in the balance.

And it seems like even semi-trustworthy Mrs. S. is working against the clones -- can she be relied upon anymore?

(Watch trailer, above.)

Season 3 of "Orphan Black" begins on Saturday, April 18 at 9 p.m. ET on Space in Canada.
