Sumino, a first-year high school student, joins a school renowned for soccer in Kamakura, but breaks his leg shortly after joining the team. Unable to participate in practice and adrift in life, he spends his days wandering around and his nights partying. One day, he meets Aoki, an older man who works at an izakaya, and gradually begins to feel emotions he has never felt before. This is the story of a summer - the best summer and the worst one - that will never be forgotten.
