This absolutely blew me away. At first I wasn't sure how into it I would be, but soon enough, I was totally transfixed. It's set during WWII and focuses on a pair of partisans who get isolated from their comrades. They have to wander around in the snow, starving, one of them ill, and do their best to avoid the Nazis. You can imagine how well that goes. The most tension-filled sequence involves their interrogation and the aftermath: who caves, who doesn't, why.
It's also a gorgeous film, shot in black and white. I've never felt like I could practically smell the snow and feel it. The lighting is beautiful, and you can see how the one, Christ-like character is illuminated as if he were an angel. It's a shame that only a few years later, this director died in a car crash.
