Ryota, Yuzuki, Kamio, and Syoya buy a bike and are in for it. They get to know the urban jungle at night as a result. They get into a van, drive into the dead of the night and are in for some violence. They want to be set free, but instead get beaten up, trampled on, crushed and cannot find a way out. They should not have gotten involved with a gang of thugs, but it is now too late. Do they have to fight back? Is it the only way out?
