Hey, #CloneClub, it’s the best time of the year! An all-new season of Orphan Black premieres tomorrow night, and we couldn’t be more excited! Last season left off with another suspenseful ending (Season 2 spoilers ahead!) that none of us here at InStyle saw coming. Although Sarah was finally reunited with her daughter and all seemed to finally be looking up for the clones, the drama wasn’t over yet. In the final scenes, we see Helena get abducted by the military, meet a new (and younger!) clone from Project Leda, and most shocking of all, are introduced to Project Castor: male clones.

The love/hate relationship between Sarah and her “sestra” Helena seemed to have finally worked itself out. So will Sarah try to save her? We were also left wondering what will become of Cosima’s illness, and whether Alison will be able to maintain control of her ever-spiraling life. Sarah’s world has become a dangerous game of trust and loyalty, and with the baffling introduction of the male clones, it’s certain to be another exciting season.

Watch the trailer above for a sneak peek at what’s in store for the clones---and don’t forget to tune in to BBC America at 9 p.m. ET on Saturday, April 18, to catch the premiere!
