Klaus, the original vampire/werewolf hybrid, returns to New Orleans — which his family helped build — to investigate rumours of a plot against him, in this spinoff of “The Vampire Diaries.” He finds his former protege, Marcel, reigning powerful over its inhabitants, causing growing tension in the supernatural community. Klaus’ brother, Elijah, joins him, and they learn that werewolf Hayley has fallen into the hands of a defiant witch who has life-changing information. In hope of reclaiming the city, Klaus and Elijah form an uneasy alliance with the witches to help further their cause.
Season three is where the real war begins. The Mikaelson’s are at risk because the last of the white oak is still out there. Klaus’ sire link has been broken and now he will have to run to the end of the earth, away from his enemies. Freya put a spell so that when the enemies locate Klaus, it will lead them to New Orleans and not where Klaus is running to with Hayley and Hope.
