A University graduate works as an office boy. One day there is a crisis between several employers in his office. With the help of his roommate, a monkey, he has to quickly find a way to solve the problem and in the process almost endangers his own life.

Mr. Os has always used animals to comedic ends in his films, none more so than in Hero, in which he forms a unique bond with a pet monkey. An elegantly simple tale of a working-class man trying to find happiness in the big city, this gentle comedy leaves a mark with its profound emotional effect.
