A dead man, walking between the worlds, foresees the end of the gods. A survivor searching for a weapon releases a demon from fiery Muspelheim. A village is slaughtered by Christians, and revenge must be taken. The bonds between the gods and Midgard are weakening. It is up to Hilda, Ragnar, their tribesmen Einer and Finn, the chief’s wife Siv and Tyra, her adopted daughter, to fight to save the old ways from dying out, and to save their gods in the process.
