Underworld: Rise of the Lycans is a 2009 American action horror film directed by Patrick Tatopoulos. It is the third (chronologically, the first) installment, and the prequel film to the Underworld series, focusing primarily on the origins of the characters and the events that lead up to the Vampire–Lycan war, depicted in the previous films Underworld and Underworld: Evolution.
The film tells the story of Lucian, the first werewolf born in human form and the first to be called "Lycan". Viktor, an elder vampire, raises the child, and envisions a race of Lycan slaves that could keep guard of the coven's fortress during the day and be used as laborers by the vampires at night. As Lucian grows up, he and Viktor's daughter Sonja (Rhona Mitra) fall in love and begin a secretive intimate relationship in their adult years.
