Youyin High School is about to usher in the new year's school festival, from teachers to students, but they are all busy for this important festival. Although there is still the last day of preparation, the opening ceremony of the School Garden Festival has not been held for a long time, day after day, year after year. The tired hot spring teacher felt strange about it. He felt that he lived the same life as the people around him every year, but he didn't notice anything strange. The hot spring told the cherry blossom teacher this idea, and the two discussed and ordered the students who soaked in the school every day to go home, but in any case, the face hall and others finally returned to the school gate, and the hot spring teacher who stayed behind also disappeared. After several days of the same weird life, the audience, Adam and others agreed to set up a truth picket group with the cherry blossom teacher, and everyone entered Youyin High School, which is particularly strange in time and space. The film is based on the original work of cartoonist Rumiko Takahashi and is the second film version of the series. Director Ai Shou's new interpretation of the film has aroused the dissatisfaction of the original author.
