Keiko, a young pro boxer, was born with a hearing impairment. Boxing is a real challenge for her, but the club she belongs to is like a second home. After winning two difficult fights, a creeping fear begins to grow inside her. The club chairman, the only person who had accepted her as a boxer, is plagued by health issues and is losing his eyesight. Having learned that the gym is about to close for good, a confused Keiko goes on to her third bout. But perhaps the biggest challenge she faces is trying to understand the true nature and strength of her will to fight.
