The devil's school is similar to a human school in many ways. Restless students, a strict and constantly frowning headmaster, an indulgent class teacher who won't let his students down. The trio of high school graduates from our fairy tale are given an extremely difficult task. They are to capture the sinful souls of a baker and a miller for hell. But the eloquent Miss Cordelia gets in the way of the devils, the baker, and the miller, and the completion of the devilish tasks is suddenly in jeopardy. The students must figure it out for themselves. If they fail the final graduation exam, they will be the laughing stock of hell, and they will also face another thirteen years of school. And that is a hellish punishment.
