Set during the World War 2. In the summer of 1941 the Finnish army crosses the border of Russia. A platoon led by Lt. Eero Perkola goes through the wilderness around the Lieksa lake to search for Russian defensive positions. The platoon kills some Russian civilians and rests in a newly conquered village. There Lt. Perkola meets his fiancée Kaarina, who is serving in the Women's Auxilary Corps (Lotta). Then the platoon continues with the mission, but a message about Kaarina's possible death reaches Lt. Perkola. The message causes Perkola to become distracted during the mission.—Anonymous
