一個100円店女店員的《激戰》故事。女主角一子是個不修邊幅的32歲廢柴中女，無人無物無目標的她就像她工作的100円店的貨品一樣cheap。直至遇上經常來買香蕉並在附近打拳的超齡拳手狩野(新井浩文飾)，撩動她春心之餘，竟激起她的一團火，雷台鐘聲更敲響了遺失的自尊。女主角是《愛之剝脱》(第六屆)中嶄露頭角的安藤櫻。比起《激戰》中的張家輝，安藤櫻不單在開拍前接受拳擊訓練三個月，拍攝時更要增肥後再操fit，猶如激戰真人騷。導演武正晴從四百位應徵演員中精挑而出女主角人選，百變女王安藤櫻演出甚俱說服力，令觀眾拍案叫絕，在日本奪得多個最佳女主角獎項。此片將代表日本角逐2016年度奧斯卡最佳外語片。

A young slacker takes the long road to rock bottom before boxing her way into a glorious rebirth in this critically acclaimed dark comedy, the top winner at the Japanese Splash competition of the Tokyo International Film Festival. In an astonishing performance, Ando Sakura (Penance, Love Exposure) stars as Ichiko, a hopelessly out-of-shape slacker who leaves home and begins working at a third-rate 100-yen shop. After living through an abusive relationship with a boxer (Arai Hirofumi) and a traumatic incident, Ichiko finally decides to pick herself up by training to become a boxer. A trained boxer in real life, Ando absolutely delivers the goods in the spectacularly cathartic finale.
