32-year-old Ichiko (Sakura Ando) lives at home with her parents, passing the days in self-indulgent grunginess. Ichiko’s recently divorced younger sister Fumiko has moved back home with her young son. One day, after a particularly heated argument, Ichiko charges out of the house for good. With few employment options to support herself, Ichiko works the night shift at a 100 yen shop (dollar store). On her way home each day she passes a boxing gym where she watches Yuji Kano (Hirofumi Arai) silently practice, developing a crush on him. The pair starts seeing each other and things change for Ichiko… At last, the bell rings and longtime loser Ichiko’s rematch with life begins!
