Kate Beckinsale stars in Underworld, a stylish, suspenseful action thriller that depicts a world populated by a secretive clan of modern, sophisticated Vampires whose mortal enemies are the Lycans (werewolves), a shrewd gang of street toughs. Selene (Beckinsale), a beautiful Vampire warrior with the strength of ten men, is a death dealer, assigned to hunt down and eradicate the wolf-people. But the balance of power is upset when she falls in love with the nascent Lycan she's been tracking, Michael Corvin (Scott Speedman). When she figures out that he holds the key to ending the centuries-old war, Selene must decide where her allegiances lie. Len Wiseman directs this fast-paced tale of deadly action, ruthless intrigue and forbidden love.
