Bright young soldier Mertsi suffers a permanent brain injury in the Second World War. In the late 1940s he wanders around the Finnish countryside looking for simple work and relying on other people's help. A workmate, Ville, tells him about his clever Spitz dog back home and the problems with her overlong dew claws. Together with his helpful war buddy Eetvi, Mertsi joins a lumber camp in the middle of a freezing winter, tries hard but finds the work there too strenuous for his body and mind.
