Spoiler Summary:
Set several years after the events of Underworld: Blood Wars, the fragile truce between vampires and Lycans is shattered when a new breed of hybrid, known as the “Dark Bloods,” emerges. These creatures are the result of forbidden experiments combining ancient vampire DNA with mutated Lycan traits, making them faster, stronger, and nearly impossible to kill. Selene (Kate Beckinsale), having vanished after the last war, is forced out of hiding when the Dark Bloods begin slaughtering both vampire and Lycan leaders, threatening to end both species.
Selene’s return is met with suspicion, especially as rumors swirl that she may have been involved in the creation of the Dark Bloods. She reunites with David (Theo James) and Michael Corvin (Scott Speedman, rumored to return), forming an uneasy alliance with old enemies. The group discovers that the true mastermind is a resurrected vampire king, long thought dead, who seeks to use the Dark Bloods to establish a new world order.

As the Dark Bloods overrun the ancient covens, Selene must confront her own legacy and the consequences of immortality. In a climactic battle set in the ruins of an Eastern European castle, Selene sacrifices herself to destroy the source of the Dark Bloods, but not before passing her powers to a new generation. The film ends with the vampire and Lycan survivors forming a council, vowing to end the cycle of war—at least for now.
