Wer hat Angst vor Rot, Gelb, Blau?

Berlin painter Banuscher has been rather moderately successful so far. He has only been able to keep his head above water thanks to the financial support of his girlfriend Francis. She then organizes his first exhibition, which is finally a success. Instead of gratitude, however, Francis is given the boot by Banuscher. She doesn't want to put up with this and swears revenge. And what could be better suited for this than the artworks of the vain Banuscher?
