Knock on the Door (1990)

...1949. Baulin, a school principal in a small Moldovan town, is summoned at night to the district party committee. He is tasked with leading a group that is carrying out an action in the area to evict so-called fascist collaborators. We will see only a day in the life of the main character. He walks around the huts, sees people included in the “black lists”, understands that they could not possibly be traitors.
