November 9, 2022. At Sakurazaka46's Tokyo Dome concert, some girls in the audience shed tears as they watched the performance. The 11 girls are the third generation of members who passed the audition because they wanted to be a part of Sakurazaka46. Looking at the stage they will soon be standing on, they feel a mixture of anticipation and anxiety. However, at the intensive training camp that began the next day, these feelings were mostly dominated by anxiety. The dance was more difficult than they had imagined, their determination was lacking, and harsh words. Though the road ahead was difficult, they took the first step towards becoming Sakurazaka46, believing that they would one day shine on stage.

Five days of the Sakamichi Group's longest training camp ever has begun. BAN's choreography, which was said to be reckless, was so harsh that it deprived them of their appetite. "That was terrible." The members couldn't stop crying when the instructor pointed their mistakes out one after another. Emotions are high as they work on technique. It is only the 2nd day and they are already feeling the pressure.

An entire day of lessons and self-practice are starting to slowly come to fruition. Although they are still uneasy, their improvement can be seen from the sidelines. At night, the 3rd gen members take a break and make dinner. They are working together for the first time. Their appetite has recovered, and the mood has lightened up. They want to show their full potential to Takahiro-sensei, who is coming to observe the lesson the next day. With that in mind, the members practice hard in private after the day's lessons and take a firm step forward.

One more day until the reveal of "BAN." On this day, Takahiro-sensei suddenly came to see how the lesson was going. In the tense atmosphere, Takahiro-sensei watched the lesson in silence. The members gradually began to show their unique qualities, and finally the group began to shine. "Dancing to BAN is just too much! But you're gonna do it, and you must be ready to fight." Thus the story began. What happened on the day of the reveal? And so begins Chapter 2 of this story.

The training camp is over. They crossed the first wall. Only to be greeted by a new wall. They now have the new mission of completing the full version of BAN. Moreover, the production of 3rd generation music videos depends on the quality of this performance. They improved their individual skills at the training camp. Now, they train to improve their group cohesion. Different formations raise the difficulty and new problems arise. The members struggle to find a solution as they realize the difficulty of functioning as a group. Meanwhile, the day has finally come to meet their seniors. As the captain Matsuda and the other 1st and 2nd gen members greet them cheerfully, what's going through the minds of the 3rd gen members?

They finally meet the 1st and 2nd gen members for the first time. After having admired them for so long, the 3rd gen members are overwhelmed with emotion. The reason lies in the hearts of these girls that aspired to become one with Sakurazaka. Just what does Sakurazaka mean to each of them? And it was the last lesson before they attempt the full version of BAN. Takahiro-sensei points out the areas where they are still lacking. How to behave on stage, stage awareness, supporting other, the final push to becoming a pro. Tomorrow, all 11 members give their absolute all to bring the 3rd gen BAN to perfection.

It is the day of the reveal. These 11 girls who couldn't even dance before now stand with determination in their eyes. From the looks in their eyes, one could feel a fire inside, a fire that will drive Sakurazaka to new heights. And the result of 100 days of work was over in an instant. They have devoted themselves to countless lessons for their song to bloom for just this one moment. Yes. This now their life. They will keep running, keeping searching for that one moment to bloom.

172 days from the announcement of the results to the release of the single on February 15th. 11 people have always supported each other. Even if there are members who can't participate in the training camp, I will do my best to support them, encourage each other even if there are members with painful feelings, we were connected by heart. And there were always two people who could not be seen in the main part of the documentary. +2 Another Story. Due to academic reasons, the documentary and the music video for 3rd gen member song "Natsu no Chikamichi" Another story that focuses on two people who could not show their true faces. In addition, the state of the music video shooting of "Natsu no Chikamichi" which was not drawn in the main story, this is a special edition that includes members watching the completed video.
