A Proletarian Winter's Tale(2014)

Three young Georgians have to clean a castle in Berlin, where a German arms manufacturer's art collection is being set up for an exhibition. Of course, the proletariat isn't welcome at the opening party and they are banished to a servants' room in the attic. Downstairs, however, a splendid buffet attracts them - so why not just ignore the unfair prohibition and cross the line of class society? Didn't the French Revolution start over a piece of cake?
