Build a movie plot around this: Why does David want Selene to stay? To help rally the vampires and fight back.
This latest addition to the 'Underworld' series opens six months after the events of the second movie, Underworld: Evolution. The vampire Selene is captured by humans during "The Purge," a massive crusade of war to exterminate vampires and lycans after mankind learns of their existence. Humans call Lycans "Non-Humans" and Vampires are called "The infected."12 years later, it is revealed that human governments all over the world had committed genocides to vampires and lycans, killing everything.
