The third season of BBC breakout Orphan Black has shared a few photos and teasers of its April 18 premiere, but today goes all-out to send in the clones. Preview Season 3 of Orphan Black with its first official trailer, and a brand-new poster and synopsis to boot!

There’s a lot to take in by the full trailer and extended synopsis for Orphan Black Season 3, so we’ll dive right in:

After neutralizing the threat by the DYAD Institute (the company that monitored them) – Sarah, Helena, Cosima and Alison (Maslany) are finally all united in their journey towards the truth of who and what they are. But new discoveries that include Helena’s kidnapping, a book that could contain the answers to their existence and the most shocking discovery of them all – a set of treacherous male clones with an unknown agenda – will test how tight their new bonds are.

No sooner has Sarah caught her breath after a stealthy escape from DYAD and the ruthless clone Rachel (Maslany), she is called upon to face the crazed, captive Castor clone, Rudy (Millen). But it is the discovery of Helena’s disappearance that spurs Sarah into action, rallying her sisters in the quest to reunite their clone family, and find peace once and for all.

Their greatest threat is a band of highly trained soldiers – identical brothers dubbed Project Castor. Unlike the sisterhood, Mark, Rudy, Seth, Miller and others (Millen) grew up together, fully aware of who and what they are. Developed by the military, this wolf pack was raised as regimented clones – singular in thought, movement and allegiance. Hell-bent on kicking up dirt, they’re dispatched to tackle their mission from all sides. But differences in approach betray cracks in their armor, and may be the very thing the sisters need to escape their clutches.

The sisters will need all the help they can get. With Cosima’s fluctuating health and no known cure for the mystery illness that ails her, she is holding onto life by a thread while nursing a broken heart left by her scientist lover Delphine (Evelyne Brochu). Can she find a cure in time to save herself and her sisters? As the turbulent world of Alison turns, she faces fresh suburban woes and new marital challenges with lovable oaf of a husband Donnie (Kristian Bruun). How far will Alison go to keep up the façade of her cookie cutter life? Sarah’s torn between her desire for a life with daughter Kira (Skyler Wexler) and Kira’s father Cal (Michiel Huisman) and the urge to protect her foster family – loyal and feisty brother Felix (Jordan Gavaris) and mother Mrs. S (Maria Doyle Kennedy). But Mrs. S’s betrayal may cause her to turn her back on the only mother she’s known.

Not enough? How about a breakdown of the new male clones?!

MARK (Ari Millen), one of the newly discovered Castor clones, was a loyal follower of the late Prolethean leader Henrick Johanssen. When the Prolethean Ranch was burned down by Helena, Mark vanished with Johanssen’s waifish daughter Gracie, who he’d fallen deeply in love with. But as one of many male clones created by the military, the question remains, who is Mark? Why was he with the Proletheans? And in the face of this newfound love, where do his allegiances lie?

RUDY (Ari Millen), aka Scarface, is the often brutal and crazed Castor clone with a sleek mohawk and a menacing scar that adds to his intimidating exterior. Raised under the military’s unforgiving supervision, Rudy is a trained master fighter. Possessing a fierce loyalty to his clone brothers that matches Sarah’s conviction, he is ruthless and lethal if put to the test. Just how far is he willing to go to save those he’s sworn to protect?

SETH (Ari Millen) is a mustachioed Castor brother who may not be the sharpest clone in the pack. But what Seth lacks in smarts, he makes up for in obedience to his superiors, and admiration for his elder brother, Rudy — who sometimes uses Seth’s devotion to sway and manipulate him.

MILLER (Ari Millen) is the spit-and-polish Castor soldier with a prosthetic leg. No longer assigned missions in the field, Miller is bitter but loyal. Refusing self-pity, he focuses his efforts on climbing the officer ranks.

It gets even better! The first two synopses of the season:


Sarah pursues the missing Helena who is held in a faraway compound. Sarah must use her wiles – and acting chops – to deter a Topside investigator who threatens the Leda sisters’ lives. Meanwhile, Cosima appears to be rebounding from her illness, while Alison and Donnie face newfound financial woes. But when the menace of Castor rears its head once more, Sarah and her entire family must come together to survive. Episode One premieres Saturday, April 18, 9:00pm ET on BBC AMERICA.


Castor pursues the Leda clones for original tissue samples. Helena, who is pregnant and imprisoned, is examined by a mysterious new villain. The Castor boys are also out to play, toying with a frightened young woman, Patty, in a sexy switcheroo that ultimately sets Sarah – and Art – hot on the Castor trail. But it’s not all fun and games for the Castor boys, as Sarah gleans they may have a mysterious defect that puts their lives in peril. Episode Two premieres Saturday, April 25, 9:00pm ET on BBC AMERICA.

As for the new faces this year, Shameless star Justin Chatwin will play Allison’s high school flame Jason Kellerman, while True Blood vamp James Frain will provide a deadly threat to the girls as “cleaner” Ferdinand. Additionally, Black Swan star Ksenia Solo will portray Cosima’s healer friend Shay, joining Warehouse 13 alum Kyra Harper as the military’s Dr. Coady, and Earl Pastko as Ferdinand’s bodyguard “Bulldog.” Game of Thrones star Michiel Huisman will also return as Sarah’s baby-daddy Cal, while Evelyne Brochu is confirmed to reprise her role of Cosima’s scientist lover, Delphine, now leading the Dyad in Rachel’s absence.
