Heizi works at the Banshu Akagokubutsu Company, led by President Asano, together with classmates Riko and Miki from the high school dance club, in their third and fourth years. Yoko, a widowed and slow-witted cleaner, is their senior, and the four of them continue to dance as they did in their youth. Suddenly, Kira, president of the Kira General Trading Company, appears with a powerful female bodyguard. If Kira's company stops doing business with him, Asano will go bankrupt immediately, which is the reason Asano cannot hold his head up high. Kira calls Riko into another room and offers her a position as his company's secretary. Reiko continuously refuses, wanting to dance at Asano's company. Asano, who was checking the situation outside, becomes furious and rushes into the room, only to be attacked by Kira and the female bodyguard. Heizi, worried, runs in and finds the raped Heizi and the dying Asano, and challenges Kira. In response to Heizi's assault, Kira shouts that he won't be despicable anymore, but then Yoko screams that the female bodyguard is dead. Kira's loud laughter echoes. Two years later, Heizi is released from a women's prison and reunites with Miki and Yoko. During Asano's imprisonment, Heizi passed away, and the company disappeared. Reiko took over her mother's debts and became Kira's mistress. Yuko, the dance club advisor, also arrives. Heizi cries for his sins and Yuko's maternal love. Eventually, Heizi works at a printing company run by senior member Arisa, who also lost her husband because of Kira. They hit it off, and Heizi and the others decide to pursue their dancing dreams again. Following Yuko's advice, he works towards the goal of dancing at a memorial event at school. On the other hand, Kira hears that Heizi has been released...
