UNDERWORLD: RISE OF THE LYCANS delves into the origins of the centuries-old blood feud between the aristocratic vampires, known as Death Dealers, and the barbaric Lycans (werewolves). A young Lycan, Lucian (Michael Sheen), emerges as a powerful leader who rallies the werewolves to rise up against Viktor (Bill Nighy), the cruel vampire king who has persecuted them for hundreds of years. Lucian is joined by his secret lover, the beautiful vampire Sonja (Rhona Mitra), in his battle to free the Lycans from their brutal enslavement.
