The peaceful realm of Azeroth stands on the brink of war as its civilization faces a fearsome race of invaders: orc warriors fleeing their dying home to colonize another. As a portal opens to connect the two worlds, one army faces destruction and the other faces extinction. From opposing sides, an unlikely set of heroes are set on a collision course that will decide the fate of their families, their people and their home. So begins a spectacular saga of power and sacrifice in which war has many faces, and everyone fights for something.
- 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.
