Yuzi, a documentary director, led a production team to investigate the suicide of a bullied female student three years ago and filmed several families who had lost loved ones. She was determined to undo the whole story, clashed with conservative television management, and succeeded in getting her interviewees to trust her. However, she found that her father, Kinoshita, who ran the cram school, had made a serious mistake. All this provided her with a new perspective, made her documentaries more in-depth, and even won praise from producers and television stations. But unexpected things came one after another, which made Yuzi's view of truth and lies out of balance, forcing her to make a life-changing decision.
