Selene (Kate Beckinsale) wishes to expose the truth about the death of Viktor to the first true vampire Marcus (Tony Curran) that is hibernating. However, Marcus has already awakened and wants to release his savage Lycan brother William (Brian Steele), who has been imprisoned for centuries. When Marcus tries to get the medal possessed by Lucian from Michael (Scott Speedman), Selene decides to visit Andreas Tanis (Steven Mackintosh), the exiled official historian of the covens, to understand his interest. When Selene and Michael meet Tanis, they disclose the truth about their bloodlines, and later with the support of Alexander Corvinus (Sir Derek Jacobi), Selene faces the powerful Marcus as the last hope left for the mankind.
