The Originals follows the Mikaelson siblings—Klaus, Elijah, and Rebekah—as they return to New Orleans, the city they helped build centuries ago. Klaus, a hybrid of vampire and werewolf, seeks to reclaim power from his former protégé, Marcel, who now rules the supernatural factions with an iron fist. The siblings’ complicated history resurfaces as old rivalries and alliances come into play. Meanwhile, Klaus discovers Hayley, a werewolf, is pregnant with his child—a miracle that could change his ruthless nature.
As the Mikaelsons settle in, tensions rise between Marcel’s vampires and the werewolves, who have been oppressed under his rule. Elijah, the noble brother, tries to keep peace while maneuvering political schemes. Rebekah, longing for freedom from her brothers’ control, finds herself torn between loyalty and desire for independence. Klaus, paranoid and volatile, struggles with trust, even as he forms an uneasy alliance with Hayley to protect their unborn baby.
A powerful witch named Sophie Deveraux reveals that Klaus’s child is key to breaking a curse on the werewolves, forcing the siblings into a dangerous game of magic and betrayal. Davina, a young witch under Marcel’s protection, holds dark secrets that could shift the balance of power. Meanwhile, a mysterious enemy from the past—the witch Esther, their mother—returns with a vengeful plan to destroy her own children.
The siblings face threats from all sides, including their estranged brother Finn and their father, Mikael, a relentless vampire hunter. Hayley’s pregnancy progresses, making her a target, while Klaus’s paranoia grows. Elijah works to unite factions against their enemies, but trust is scarce. Rebekah, caught in the middle, must decide where her loyalties lie as the family’s dark history threatens to repeat itself.
In the explosive finale, alliances shatter as the Mikaelsons confront their parents’ deadly schemes. Klaus makes a desperate move to protect his child, while Elijah and Rebekah fight to keep their family from crumbling. Hayley gives birth, but the joy is short-lived as new dangers emerge. The season ends with the siblings standing together, vowing to defend their legacy and the future of Klaus’s hybrid child—setting the stage for even greater battles ahead.
