Robert Graf plays the title role in the allegorical German drama Jonas. The hero is an anonymous worker in a huge printing plant. Feeling somewhat lost in an increasingly mechanized, impersonal world, Jonas takes to wandering around town during his lunch hour. One afternoon, he impulsively purchases a hat, which is promptly stolen. For Jonah, this is the last straw: he manifests his anger against society by stealing a hat himself. The rest of the film traces Jonah's desperate -- and unsuccessful -- efforts to get rid of his ill-gotten headgear. Virtually a pantomime, Jonas is underscored by the plaintive music of Duke Ellington.
