Eiji Kurisu (Satoshi Tsumabuki), a tax accountant who’s lost his sense of purpose after a career setback, is asked by Royal Human Corporation to investigate its struggling horse racing division. The company’s founder, Kozo Sanno (Koichi Sato), passionately supports the division, but his son Yutaro (Kotaro Koizumi) wants it shut down, while Kozo’s wife Kyoko (Hitomi Kuroki) despises it altogether.
Sent to Hokkaido to meet Kozo, Kurisu arrives late and witnesses him lose a prized horse auction to rival owner Yoshihiro Shiina (Ikki Sawamura). Drawn into Kozo’s world, Kurisu encounters a life far removed from his own—and unexpectedly reunites with his former lover, Kanako Nozaki (Wakana Matsumoto), who now works at her family’s farm.
After recommending the division’s closure, Kurisu learns from Kanako the harsh realities of horse racing. Inspired by Kozo and Kanako’s passion, he rediscovers his drive and sets out on a new path.

Later, Kozo’s son Yutaro (Kotaro Koizumi) challenges his father to win at least one central race within the year—or abolish the division entirely, citing complaints from the younger employees. Kozo accepts and takes Kurisu to the Miho Training Center to back his prized horse, *Royal Fight*. However, his pushy attitude angers trainer Tadokoro, causing a fallout.
Ordered to find a new trainer, Kurisu reconnects with his former lover Kanako (Wakana Matsumoto) in Tokyo, who introduces him to a talented trainer named Hironaka (Masanobu Ando). Kurisu visits Hironaka’s stable, unaware that this meeting will change everything.

Amid this, Kurisu and Hironaka place their hopes in a particular individual: Saki (Mahiro Takasugi), a blond jockey from the Iwate racing circuit. However, not only is it difficult for a regional-circuit jockey like Saki to obtain a central racing license, he also caused a certain trouble in the past...

Meanwhile, a scandal also comes to light at Royal Human, and Yutaro (Kotaro Koizumi) moves to deal with it...

Despite Kurisu's efforts to arrange another meeting and propose a solution, Koichi remains resistant. Determined to break through, Kurisu pulls Koichi aside for a heart-to-heart, and the truth finally comes pouring out. What Koichi reveals shocks everyone, including veteran trainer Hironaka.
