Hószakadás (1974)

In the summer of 1944, a Hungarian soldier commits a murder to earn a short leave from the front, but instead of returning, he chooses to desert. He flees into the desolate Carpathian Mountains with his elderly grandmother, searching for a hidden cave where his parents are rumored to be hiding from the war. Convinced that the world is ending, the pair struggles through the brutal, wintry landscape in a desperate attempt to find sanctuary and outrun the consequences of his actions.
