Le jardinier (1981)

This is a surreal comedy is about a factory set in a barren landscape that dispenses a minute portion of water to stragglers carrying pans as receptacles. Inside, the workers seem to be doing nothing that makes any sense, and they are watched over by a periscope set up by twins who run the factory. An unexplained, plain woman living on the premises is sought after by the whimsical foreman (Maurice Benichou) -- also known as the "gardener" because he has planted flowers in the coal wagons that remain on a maze of train tracks -- the only "stock" owned by the company.
