Affected by the powerful images in the pamphlet 'If war comes', farmhand Karl-Göran Persson begins fortifying his house. Through years of harvesting scrap-metal, he transforms it into a fortress meant to protect him and his neighbors when the enemy attack or the disaster comes. Apart from the children in the village who sense the urgency of his actions and mirror them in their own games and fantasies, Karl-Göran’s efforts are met with suspicion, bewilderment and hostility.
