The CW has released an official synopsis for season three of The Originals, you can read it below!
The Originals will be back in October, 2015 with its new season, and below you can read the description:
The Mikaelson family tragedies and triumphs continue as THE ORIGINALS enters its third season. The Original vampire-werewolf hybrid Klaus Mikaelson (Joseph Morgan) and his brother Elijah (Daniel Gillies) have spent one thousand years fighting to protect their dysfunctional family, but now that Klaus and the hybrid Hayley (Phoebe Tonkin) share an infant daughter, Hope, the stakes are higher than ever. In the second season, Klaus and Elijah united against their resurrected mother, Esther, who tortured them with demons from their pasts in an effort to persuade them to surrender their vampire bodies and become mortal. Esther, however, was only the harbinger, as Klaus learned that a long-standing curse had marked Hope for a life of isolation and terror at the hands of Esther’s sister, the witch Dahlia, whose defeat came at great cost to the family. Season 3 finds Klaus and Elijah estranged from each other, even as both brothers adjust to life with their long-lost sister, Freya (Riley Voelkel). Hayley suffers mightily at the hands of Klaus’s petty vengeance, while Marcel (Charles Michael Davis) and Davina (Danielle Campbell) rule the city under a new status quo. Meanwhile, Cami (Leah Pipes) and Vincent (Yusuf Gatewood) find themselves caught up in a surprising mystery involving the newest resident of New Orleans — the first vampire ever sired by the Mikaelsons a thousand years ago. 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”), Diane Ademu-John (“Body of Proof,” “Medium”) and Leslie Morgenstein (“The Vampire Diaries,” “Gossip Girl”) are executive producers.
