Honza Vavrinec (Rudolf Hrusínský) works in the investment department of a large office. One day he gets involved in the case of an unjustly convicted worker who mistakenly considers him a parliamentary deputy. Honza as a "deputy" interferes in the case and helps the worker. Encouraged by the success and possibly also out of love for the beautiful secretary Svatava (Blanka Bohdanová), the then shy and fearful Honza stands up for the chief of the department, Hofmánek (Ladislav Pesek), who has been removed from his position.
