Signs of Life (1968)

During World War II, three German soldiers are withdrawn from combat when one of them, Stroszek, is wounded. They are assigned to a small coastal community on the Greek island of Kos while Stroszek recuperates. The men become increasingly stir crazy in their uneventful new assignment. Stroszek eventually goes mad.
