Affected by the powerful images in the pamphlet Om kriget kommer (If war comes), farmhand Karl-Göran Persson begins fortifying his house. Through years of harvesting scrap-metal, he transforms the house into a fortress, meant to protect him and his neighbors when the enemy attacks. As the task progresses, reality and the threat of future destruction become intertwined, and construction becomes an obsession for the lonely Karl-Göran.
