In the new semester, the "Gang of Three" formed by Lin Haoxuan, his best friends Wang Dalong and the ghost Ma Tiantian is famous for playing tricks on teachers and the school system. The arrival of transfer student Xu Kexin broke the delicate balance among the three, and also brought about a competition between academics and friendship. Various activities, exams, emotions, and family on campus test them one by one. Behind the humorous daily life, everyone has grown into people who understand more responsibility and choice. They experienced all kinds of ridiculous farces together and relied on each other at critical moments. As the senior year of high school approaches, dreams and reality alternate and collide. Finally, in the summer after the college entrance examination, everyone bids farewell to campus and welcomes a new chapter of life with a more mature attitude.
