The Wave

Geologist Kristian Eikjord is working his final day in the Norwegian tourist destination Geiranger before moving to Stavanger with his family, when sensors on the mountain indicate groundwater has disappeared. Later, waiting for the ferry with his children while his wife Idun works a few more days at the hotel, Kristian has an epiphany and rushes back to the geology center, leaving his children Sondre and Julia in the car. He and Jacob take the helicopter and find the sensor wires have snapped. Kristian's former boss Arvid agrees to enter a higher state of alert, but not to sound the evacuation alarm.
