It is the summer of 1941 and the Finnish army has been mobilized along the border with Russia. A platoon led by Lt. Eero Perkola is waiting for orders to go on the offensive. The platoon receives orders for a recon mission through the wilderness around the Lieksa lake to search for possible Russian defensive positions. When the platoon rests in a newly conquered village Lt. Perkola meets his fiancee Kaarina Vainikainen, who is serving in the Women's Auxilary Corps (Lotta). The platoon continues with the mission, but after some time a terrible message reaches Lt. Perkola. The message causes Perkola to become totally indifferent to his and his platoon's safety during the remainder of the mission. Written by Anonymous
