In the mountains of Romsdalen, Norway, Tobias takes his daughter Nora to visit "The Troll Peaks," where trolls once turned into mountains. Years later, Nora is an archaeologist on a tough expedition on the Atlantic coast. Despite setbacks, Nora's persistence leads her team to discover a dinosaur skull. Nearby, a construction group triggers a collapse while building a railway through the Dovre mountains, sparking seismic activity detected by the Norwegian armed forces.
