Description from the DVD (It does a better job than I do)
1944, in a land torn apart by war, a Finnish sniper is labeled a coward by his compatriots; as punishment, he is nailed to a rock and left to his own devices. Not long after, a disgraced Russian Captian, en route to his court martial, is injured in an accident. Wounded and emotionally torutred, they are taken in by Anni, a young resourceful war widow, who offers shelter to one while nursing the other back to health.
Absolutely great movie. The cinematography, the dialogue and the acting. I may show this to my students...Try to find an excuse to anyways...
