Underworld: Blood Wars is a 2016 action horror film directed by Anna Foerster from a screenplay by Cory Goodman, based on a story by Kyle Ward and Goodman. It is the sequel to Underworld: Awakening (2012) and the fifth installment in the Underworld film series. The film stars Kate Beckinsale, Theo James, Lara Pulver, James Faulkner, and Charles Dance.

The remaining vampire covens are on the verge of annihilation by the Lycans. Both species are searching for Selene: the vampires seek justice for the death of Viktor, while the Lycans, led by Marius, intend to use her to locate Eve, whose blood holds the key to building an army of vampire-werewolf hybrids.

Semira, a council member of the Eastern Coven, asks Thomas to plead Selene’s case before the council. The plea is successful and the council reluctantly agrees to a pardon in exchange for Selene’s help. Selene arrives with David and starts training the coven’s neophyte Death Dealers for the upcoming war. Semira and Varga, her ally and lover, later poison Selene, slaughter the trainees and frame her for the atrocity. With Selene in her custody, Semira begins draining her blood, intending to drink it to steal her power. Thomas and David attempt a rescue and manage to save Selene. Unfortunately, Thomas dies in the process.

David and Selene take refuge at the Nordic Coven, pursued by Alexia, an Eastern Coven vampire dispatched by Semira. At Var Dohr, the Nordic Coven stronghold, Elder Vidar reveals that David is the son of Grand Elder Amelia. She and Thomas were in love but were forced to hide their relationship and David’s true origins due to Victor’s extreme jealousy and possessiveness over Amelia. This makes David the legitimate heir to the Eastern Coven.
