When a group of young filmmakers witness and film a crime of passion, the most outrageous blackmail of the century begins. By means of a fantastic plan, the filmmakers send to the murderer, a financial and industrial big shot, a copy of the movie that incriminates him and they demand him an improvement of the standard of living for the working class.
