When the war broke out in 1940, the troop of Corporal Gunnad Tofte transferred to Narvik and was returning home for his son's birthday. He was supposed to be on vacation but was canceled because of the sudden threat from the Germans. In his vow to fulfill his duty and obligations, he has reunited with his family for a short time. When he returned to his base he was surprised when they were attacked by Germans invading their territory, violating neutrality, and even sinking a Norwegian ship.
Ingrid, on the other hand, found out that her workplace was invaded by the German army making the place their headquarters. She was even forced to help a British woman as being worried for the safety of her family and tried to leave the town only to find out that the Germans blocked the borders of the town.
As the Norwegian army knows that the German is in Narzik only because of Iron Ore. Major Omberg (Henrik Mestad) tasked Corporal Gunnar to lead his troop in destroying the bridge and he, later on, found out that his wife and his son were on a train that was supposed to pass in the bridge. Luckily they prevented the demolition in time wherein they found a group of people walking across the bridge.
Although his wife and his son appeared to pass the bridge safely Corporal Gunnar was held in prison by the German army.
In the continuation of the story, Ingrid begged the Germans for the release of his husband while trying to protect her son against the violent war they are facing. The movie does not just captivates the heart of people with the struggles of the soldiers during the war but also the sacrifices of a mother trying to protect her child against the danger of the world.
