In the grim darkness of the 41st Millennium, the only force that stands between humanity and alien hordes are the genetically enhanced super-soldiers known as Ultramarines. But when a select squad of scarred veterans and raw recruits responds to a distant planet's distress beacon, they'll discover that a horrific evil has been unleashed. And amidst a living nightmare of chaos, carnage and daemonic fury, these steel battle-brothers must now survive the ultimate enemy: Themselves. The voices of Terence Stamp (SUPERMAN II, WANTED), John Hurt (ALIEN, HELLBOY) and Sean Pertwee (DOG SOLDIERS, EVENT HORIZON) star in this intense CGI animated sci-fi/action thriller and the first-ever feature-length movie interpretation of the Warhammer 40,000 game universe.
