Uuno Turhapuro reads guide books to learn how to be an orchestra conductor and a secret agent. Meanwhile, his father in law hatches a complicated scheme to finally get rid of Uuno.
First Uuno Turhapuro film not directed by Ere Kokkonen. The reason to this was that just few weeks before the start of the movie's filming Spede Pasanen and Ere Kokkonen got into an argument about money. It ended with Kokkonen walking out of the office with the final script of the movie was written by him. Spede had to write totally new script in about a week so the filming could start.
