Orphan Black Orphan Black

The first full trailer for Orphan Black Season 3 is finally here.

Mega Buzz: Which Male Clone Could Be a Traitor on Orphan Black?

When the BBC America series returns, Sarah, Cosima, Alison and Helena (all played by Tatiana Maslany) will have to contend with Project Castor, particularly the highly lethal, Mohawk-wearing Scarface (Ari Millen), who makes an awfully creepy appearance below. But as much as Sarah might want to avoid this new threat, she soon finds herself back in the action.

"These guys are not my problem," Sarah says. "I'm sorry, they are," Delphine says.

Orphan Black returns Saturday, April 18 at 9/8c on BBC America.
