The first five films in the series charting a battle for supremacy between vampires and werewolves. 'Underworld' (2003) stars Kate Beckinsdale as Selene, one of the sophisticated groups of vampires known as Death Dealers who attempt to keep the feral Lycans (werewolves) in check. When Selene discovers a Lycan plot to kill one of the rare humans to have witnessed a vampire and werewolf battle, young doctor Michael Corvin (Scott Speedman), she sets out to protect him and finds herself increasingly drawn to the doctor and the plot that surrounds him. In 'Underworld 2 - Evolution' (2006) Beckinsdale reprises her role as Selene. With Michael (Speedman) now half-werewolf and the vampire elder, Markus (Tony Curran), planning to awaken a long-lost brother who is a Lycan, Selene and Michael face a race against time to unlock the secrets of their bloodlines and prevent a potentially deadly war between the Lycans and Death Dealers. The events of 'Underworld: Rise of the Lycans' (2009) take place centuries before those of the original film and tell of the origins of the feud between the vampires and their onetime slaves, the Lycans. In the Dark Ages, charismatic young Lycan Lucian (Michael Sheen) rallies the werewolves to rise up against Viktor (Bill Nighy), the cruel vampire king who has enslaved them. Lucian is joined by his secret lover, Sonja (Rhona Mitra), in his battle against the Death Dealer army and quest for Lycan freedom. 'Underworld: Awakening' returns to the present day and the issues faced by vampire warrior Selene (Beckinsdale). When humans discover the existence of the Vampire and Lycan clans, Selene must escape imprisonment and lead the battle to protect both species from the threat of extermination by the forces of humanity. It may well prove her toughest challenge yet. 'Underworld: Blood Wars' (2016) follows Selene as she is caught in the midst of the unending conflict between the Lycan and Vampire factions. The Lycans are preparing to mount a terrible and final war against the Vampires, intent on completely destroying them. At the head of this force there is an ambitious leader named Marius (Tobias Menzies) who intends to harvest the blood of Selene, a pure Vampire, to achieve unrivalled power. Selene and her allies must find a way to stop Marius if they are to have any chance of survival. To this end, Thomas (Charles Dance) sends Selene north to uncover a power that may save them from destruction, but time is running out, as the power her blood offers is desired by the Vampires too.
