"Dearest Dziodzio" was filmed using quotes from letters Rosa Luxemburg wrote to her lover, the revolutionary labor leader Leo Jogiches, during her stays in Poland, Germany, France and Switzerland in the years 1893-1905. With historical photo and film montages, mixed with newly shot material, the film tries to give an insight into the life problems, the thoughts and feelings of Rosa Luxemburg. The film is enriched by the recordings of the original letters, which are read out by the director, as well as by drawings, watercolors and herbaria by Rosa Luxemburg.
