This story is set in a public junior high school, which is rumored to be closed down because of the merging of area schools. The school is starting to fall apart... Teachers are so busy doing extra routine work because of personnel reduction and worrying about what to do with themselves after the school closes down, that they are not able to concentrate on teaching their classes. Students have also lost interest totally, and don't pay attention in class.

Sugi (Yusuke Kamiji) takes charge of class 2-B. When he was first appointed as 2-B's teacher, he was enthusiastic and passionate towards his job, but after several months in this school on the verge of collapse, he becomes as un-enthusiastic as the other teachers. Despite the circumstance, Kusaka (Yuto Nakajima) is the only student who doesn't give up on the school.

One day, three mysterious boys, Takasugi (Ryosuke Yamada), Yoshida (Yuri Chinen) and Irie (Daiki Arioka), are transferred to class 2-B from another school. They put some backbone into Sugi, who acknowledges that he has lost his will to teach. Despising himself for what he has become, Sugi seriously thinks of resigning, however, Kusaka's belief that the school can be changed makes Sugi have second thoughts. He starts trying to do something positive, in order to meet Kusaka's expectations.

Will Sugi and his students be able to change their school which is full of lousy teachers?
