The sun is setting on the first day of The Program, and the students of Class B are in for one hell of a night. With the failure of their initial plan to take down The Program, Shinji Mimura and Yutaka Sato are putting their backup plan in motion. Having located all the supplies necessary to create a bomb, the pair are all set to deliver their package right where it will do the most damage: the "school" which serves as The Program control center. But with the school in a permanent danger zone, will it be their bomb that detonates first... or the explosive collars locked around their necks?
