14-year-old Frieda lives with her family on the Icelandic horse farm Hohensonne. When a fire breaks out at a nearby stable, the horses are rescued—but a mare and her foal go missing. Frieda, along with her best friend Max and their Icelandic horses Alvara and Solon, sets out to find them. As they track the frightened animals through the countryside, they must overcome obstacles, gain the horses’ trust, and rely on courage and teamwork.
