When the culmination of a dark prophecy threatens their immortal lives, the Mikaelson family must stand together and face their greatest challenge yet as season four of THE ORIGINALS begins. For more than a millennium, the Original vampire-werewolf hybrid Klaus Mikaelson (Joseph Morgan) and his brother Elijah (Daniel Gillies) have fought to preserve their family no matter the cost. But after centuries, their ruthless actions have spawned a legion of enemies – and in Season Three, they returned with a vengeance. While Hayley (Phoebe Tonkin) remains at odds with Klaus over the custody of their child, she soon must choose to ally with the Mikaelsons when their long lost sister Freya (Riley Voelkel) uncovers a prophecy foretelling the family’s ruin. With the arrival of the first vampires ever sired, the Mikaelsons begin to realize that their vampire progeny have joined together to eliminate their makers once and for all. As signs around them point to the fulfillment of this dire prophecy, Cami O'Connell (Leah Pipes) finds herself thrust into the center of the conflict, even as she continues to council Klaus to reject his paranoid and merciless ways. Ultimately, the influence of the returning sire lines will take a toll on trusted allies Marcel Gerard (Charles Michael Davis), Davina Claire (Danielle Campbell), and Vincent Griffith (Yusuf Gatewood). With the Mikaelsons surrounded by enemies and prognostications of doom, they have no choice but to enact a brutal strategy that will turn everyone – friend, foe, and family – against them, thus fulfilling the prophecy itself and setting the course for season four. THE ORIGINALS is from Bonanza Productions Inc. in association with My So-Called Company, Alloy Entertainment, Warner Bros. Television and CBS Television Studios. Julie Plec (“The Vampire Diaries,” “Kyle XY,” “Wasteland”), Michael Narducci (“The Vampire Diaries,” “The 4400,” “Medium”) and Leslie Morgenstein (“The Vampire Diaries,” “Gossip Girl”) are executive producers.
