Diamonds of the Night (1964)

WWII. Together, two young men - boys, really - with only the clothes on their backs, are running toward the forest, shedding their coats identifying them as being housed at a concentration camp, while they can hear the gunfire targeted at them. As they try to elude capture which in general means their first priority being to remain hidden from anyone else, they have to deal with the necessities of life, one who tends to focus on his hunger, while the other his physical pain in wearing ill-fitting shoes, which by chance he got by earlier trading the other for food just before their escape. The one focused on his hunger is prone to delusion about what he feels he needs to do to survive regardless of if he goes through with those thoughts, and about life still in his concentration camp identified coat but out and about in general society.
