An age-old war is reignited when a young farmhand unwittingly opens a gateway between our world and a fearsome race of giants. Unleashed on the Earth for the first time in centuries, the long-banished giants strive to reclaim the land they once lost, forcing the young man, Jack (Nicholas Hoult), into the battle of his life to stop them. Fighting for a kingdom, its people, and the love of a brave princess, he comes face to face with the unstoppable warriors he thought only existed in legend... and gets the chance to become a legend himself.
