Hui Buh, a character created in 1969 by Eberhard Alexander-Burgh author and star of a radio series and book series popular in the 1970s, stars in a film that combines live action and animation. Hui Buh has been scaring people for over 500 years in Burgeck Castle as the castle's only officially licensed ghost. The problem is that he isn't very good at his job, and you can't scare anyone. Things become complicated when King Wedding spoils Julius and Leonora, causing the King to destroy the license and the ghost Hui Buh to lose power. To recover, you must pass a special examination in two days or you will perish forever.
