DCI J. Hunter Goram is a charismatic British detective of Indian descent. He and his team endeavor to solve a series of gruesome murders that seem to have connections to Norse mythology. Goram discovers a group of weekend warriors who immerse themselves in Viking history and religion, and practice fighting with authentic weapons and armor for fun. However, their role-play turns deadly when their leader twists the mythology to suit his own plans. One by one, the men submit to ritual sacrifices, leaving their tortured bodies for Goram to analyze. On the eve of Winter Solstice Goram catches up with the killer for the final sacrifice. The explosive surprise ending will have you wondering why you can't help but empathize with the killer, despite the horrific nature of his crimes, and ask yourself what you might do if faced with the events and decisions leading up to the completion of Sif's Task.
