Sinopsis: Junior high student Harada Takumi (Hayashi Kento) is a pitching prodigy, but his attitude and arrogance alienates him from schoolmates and even his own family. His father (Kishitani Goro) is completely uninterested in baseball, and his mother (Amami Yuki) spends most of her energy fussing over his ill younger brother (Yarita Akihiro). Takumi finally finds a friend and partner in classmate Nagakura Go (Yamada Kenta), a catcher who greatly admires Takumi's pitching. Together they form a "battery" and join the school baseball team, but the friends have a falling out after a loss, bringing the team to a standstill. At this time, Takumi's brother becomes seriously ill, and his only hope is for Takumi to win the big game for him.
