Underworld

For generations, a secret war has raged between vampires and Lycans, an ancient species of werewolf. After years of fighting between the two enemy races, the vampires have seemingly gained the upper hand following the death of the Lycan leader Lucian at the hands of a vampire named Kraven, who subsequently became the second-in-command to the vampires' triumvirate of leading elders. Selene, a member of an elite group of vampire assassins known as "Death Dealers", longs for revenge against the Lycans, who murdered her parents when she was a child.
