Hospital of the Transfiguration (1979)

The film is set in 1943 in a mental asylum in the country. But this is an unusual hospital: there are several incurable schizophrenic cases, staff is bit strange and a writer has voluntarily entered the clinic because he is "peculiar" and a drug addict. Then the German Gestapo arrives. The commandant 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 Nazi soldiers appear.
