Spitball Army

from the Wikipedia page for the film:

Diamonds of the Night (Czech: Démanty noci) is a Czech 1964 film about two boys on the run from a train taking them to a concentration camp. It was director Jan Nemec’s first full-length feature film.

Diamonds of the Night begins with two young men fleeing from a train taking them to a concentration camp. The film employs little dialog and the boys escape through rugged and unfamiliar terrain is interpolated with dreams, memories, hallucinations, fantasies, and flashbacks. They encounter a woman on a farm and one boy struggles with thoughts of murder and rape before silently taking a loaf of bread from the woman’s kitchen and leaving. Eventually, the boys are caught by members of a local shooting party. The men prepare to execute the boys, but simply laugh as they walk away instead of executing them. The ending is ambiguous: The men either actually spared the boys, or they could be walking into the afterlife.
