The film is based on a legendary school film of Tomáš Vorel, called INg (1985). The storyline stays the same - a young engineer finds a new job and wants to work, this proves to be impossible in the last days of the communist era.

The full-length film which, though based on Mozart's opera Don Giovanni, is more about the complexity of the time and the world. We witness the creation of a modern production of Don Giovanni, reflecting the controversial present. Mozart's exciting music, uninhibited erotic, and the eternal struggle against evil which constitutes the energy of our existence.
