Aussig (2010)

It's about ketchup

A black comedy set in Ústí nad Labem tells the story of the relationship between a Russian and an American lecturer at a local university. Both are forced to live together in a small room in a dormitory. Tension builds between them, fueled by their vastly different personalities and mutual antipathy. Disagreements arise from trivial arguments and disagreements, from adding ketchup to food to how to treat women. It's as if another Cold War has broken out on the battlefield of their cramped dorm room.
