The Valhalla music festival commemorates a long-ago Viking slaughter, but when strange things start to happen it seems the massacre may be far from over. When festival-goers begin to disappear, and musicians find themselves playing mysterious and ancient songs as if possessed, the fans have to figure out what's going on before the festival site's haunting past comes back for blood.
