Six months after the events ofUnderworld: Evolution, vampire Selene is captured by humans during "The Purge", a mass crusade of extermination of vampires and lycans after mankind learned of their existence. Twelve years later, Selene is freed from cryogenic suspension and escapes the medical corporation Antigen. The corporation is trying to make an antidote for the virus that creates vampires and lycans. Selene starts to have strange visions after her escape which she follows. She believes the visions are linked to her lover, the vampire-lycan hybrid Michael Corvin. The visions lead her into a building where she meets David, a fellow vampire. While talking to David, Selene has another vision, this time the person is cornered by lycans. Following the vision she discovers a young girl named Eve, later revealed to be a hybrid and Selene's daughter. David, takes them to his coven.

David's father Thomas does not welcome Selene and Eve, claiming Michael died twelve years ago and Selene is the cause for the destruction of the vampire clan. Dr. Jacob Lane, director of Antigen, is revealed to be a lycan alongside his son Quint, the antidote is actually to make lycans immune to the deadly effects of silver. However, Eve's hybrid genetic code is required to achieve this, so Lane sends Quint with other lycans to the vampire coven. Numerous vampires are slaughtered, Selene meets Quint who transforms into a gigantic "super lycan", his body changed by injections using Eve's blood. Selene is defeated, Eve is captured by the lycans, and David is mortally wounded during the battle. Selene decides to save Eve, but revives David using her immortal blood, given to her by Alexander Corvinus inEvolution.

Able to survive in sunlight, Selene enlists the help of Detective Sebastian, a human who tried to investigate Antigen earlier in the film. Sebastian agrees to help save Eve, admitting he was married to a vampire until she committed suicide during the Purge. Selene destroys part of Antigen's headquarters using explosives, forcing Dr. Lane to move Eve out of the building to perform an operation to create the antidote. Selene escapes from the lycans in the building, finding Michael cryogenically frozen in a laboratory, and damages his cell to let him out. Escaping in a van, Dr. Lane is intercepted by Sebastian and then Selene who cause the van to crash. Quint arrives, transforming into his super lycan form and fights Selene.

Eve frees herself from the van and engages Dr. Lane in a fight, who has injected himself with the super lycan formula used on Quint. Sebastian and the revived David aid Eve in her fight until she kills Dr. Lane by ripping his throat out. Meanwhile Quint corners Selene but is forced to reverts to his human form, only for Selene to shove an activated silver-based grenade into Quint's body, causing him to explode. Selene goes to find Michael but learns he has already escaped, Eve sharing his vision and learns he is on the roof. Selene, Eve and David run to the roof only to find Michael has gone. Selene concludes she will find Michael, and take back the world from the humans and lycans so the vampires can rebuild themselves.
