Hospital of the Transfiguration (1979)

The film is set in 1943 in an unusual mental asylum in the country. There are several incurable schizophrenic cases, the staff is bit strange, and a writer has voluntarily entered the clinic because he is "peculiar" and a drug addict. The Gestapo arrives and the commander asks for the list of patients, sorts out the Aryan doctors from the others on a return trip, and herds everyone into trucks for evacuation to the extermination camps. A young doctor momentarily escapes by covering himself under a pile of laundry in the basement, and then escapes to the woods just as the German soldiers appear.
