There is a legend about Odin’s Gold, a treasure that disappeared during the Viking age in the mountains around Skjåk in southwestern Norway. A number of treasure hunters have disappeared over the years as a result of their greed. According to legend, the treasure is cursed. 12-year-old Runa moves from Oslo to a small town. She has to learn to control her notorious temper in order to make new friends. She is not going to cause any trouble. She will be a good girl... But on her first day in her new school Runa hits the biggest bully in class with a straight left and confirms all the prejudices against her. Runa becomes one of the three members of TRIO – along with “Ritalin Boy” Simen and his buddy Lars, who is paralyzed from the waist down. Three outsiders who go where no one else dares. TRIO becomes an exponent of justice in everyday life, while at the same time hunting for Odin’s Gold. But they are not alone; ruthless treasure hunters lurk nearby.
