Inspired by a well-known Finnish epic called The Kalevala, the story opens with a down-on-his luck hardware merchant who gets dumped by his girlfriend. She tries to dispose of his collection of Asian artifacts at an antique dealer, but this sets off a mythical series of events that turns the merchant into a warrior prince, fated to battle a demon in icy northern Finland, responsible for enslaving all of humankind. The prince is abetted - and then ultimately betrayed - by a two-faced female warrior who has captured his heart and thus carries his greatest weakness in her hands. The battle involves enchanted boxes, spectacular swordfights, and supernatural events that come together - simultaneously - in an isolated cabin on the outskirts of Helsinki and in the rural Chinese mountains.
