"Kill each other. Only the ones left surviving get to graduate. Well, that's about it."
The day before graduation, students get locked up in the music room and are told this one line. In order to seek revenge against the class that drove his fiancée to death, the seemingly ordinary music teacher transforms into a music "mad teacher". This is the first short-length drama in history to unveil the story of a teacher and students risking their lives in a full-scale school death game.
The mad teacher who was born in an intolerant modern society and students - an intense exchange between those risking their lives that directly reflects the modern society.
