Looking to escape from his dying world, the orc shaman Gul'dan utilizes dark magic to open a portal to the human realm of Azeroth. Supported by the fierce fighter Blackhand, Gul'dan organizes the orc clans into a conquering army called the Horde. Uniting to protect Azeroth from these hulking invaders are King Llane, the mighty warrior Anduin Lothar (Travis Fimmel) and the powerful wizard Medivh. As the two races collide, leaders from each side start to question if war is the only answer.
