Set against the events of the Finnish
Continuation War, the film follows a machine gun troop's journey into the Soviet Union. The troop includes the simple-minded
Hietanen, the jokey Vanhala, the cynical Lahtinen, the cowardly Riitaoja and grumpy Lehto. The film also follows the commanding officers, such as the happy and slightly senile Captain Kaarna, the young and idealistic 2nd Lieutenant Kariluoto, the calm and modest 2nd Lieutenant
Koskela and the strict and unsympathetic Lieutenant Lammio. They face many struggles, such as seeing the supportive Kaarna die in their first battle, three of the soldiers refusing to leave their punishment post during an air-raid as well as defending the trenches after the Finns have taken back parts of Karelia. Part of the way, the troop is joined by
Rokka, a Karelian veteran of the
Winter War, who also clashes with Lammio due to having little respect for military discipline despite being an excellent and capable soldier. Throughout the film, several of the main characters die. Lehto is injured during night-patrol, left behind and shoots himself. Riitaoja dies the same night when he runs off frightened and gets lost in the woods. Lahtinen dies during the winter, defending his position as his fellow soldiers flee. Hietanen is blinded by shrapnel in an artillery attack when he saves a young serviceman from being shot. His military ambulance crashes and the blinded Hietanen is gunned down by passing Russian planes while trying to save the other injured soldiers. Kariluoto dies while leading a counter-attack, and shortly afterwards Koskela gets shot while destroying a tank using a
satchel charge. ==Cast==
