In 709 A.D., in the Iron Age, a spacecraft crashes in the Viking kingdom of Herot, Norway, and the pilot Kainan (Jim Caviezel) survives. He turns the beacon on; learns the language and culture of the planet using a machine; and finds that the predator, Moorwen, that he was transporting, had escaped. While chasing the alien monster, he finds a village completely destroyed and is arrested by the warrior Wulfric (Jack Huston), believing that he killed the locals. Kainan is brought to Herot as a prisoner.
