Eleven-year-old Malte moves into a high-rise building near the sea with his mother after a divorce. His mother thinks he needs to find friends, but Malte is perfectly happy with his books on historical battles, game theory and toy soldiers. It turns out, however, that the house they moved in to is in the middle of a war zone. The children in the surrounding houses have divided the areas in two and strict rules govern all movement, especially when it comes to the skating barn. They soon realize that Malte possesses useful knowledge that can bring them benefits in the war and the conflict escalates. Nina Asarnoj at Kulturnyheterna in P1 writes: "Goran Kapetanovic's film Krig is something so rare as an intellectually challenging film for children".
