Dirt (1986)

Original title: Schmutz

"An allegory on the obsessive ousider and the banal roots of totalitarianism"

Josef "Schmutz" (german for "dirt"), a security guard obsessed with duty and cleanliness, is given the task of guarding a decommissioned industrial plant. While maintaining his devotion to the authority of property right, the self-proclaimed "Representative of Ownership" is himself slowly losing his sense of reality.
