In this live action adaptation of the popular anime, five boys face harsh punishment for seeking forbidden sights at their new, formerly all-girls high school.

The Underground Student Council has it out for the disgraced group of peepers as they do their best to cope with their "prison."

Gakuto hatches an explosive plan to help Kiyoshi escape the prison and secure his date at the sumo match with Chiyo.

As Kiyoshi deals with the fallout from his failed escape attempt, the Underground Student Council initiates Operation: DTO in an attempt to expel the boys once and for all.

Relationships are strained and tensions are heightened as Operation: DTO moves forward at full force.

Now that Operation: DTO has completed its goal, the boys must rush to find proof that they were framed before the chairman finalizes their expulsion.

With just one day left to prove their innocence, the boys amass all their resources to launch one final counterattack against the Underground Student Council.

It's all led to this; will the boys finally be able to return to their old life at the high school, or will they be forced to leave it forever?
