2017年7月。在排名战中，前崎学九段（安田显）突然陷入了思考停止的状态。无法集中于盘面，脑海中萦绕着死亡的印象。那时象棋界遇到了丑闻。在象棋联盟担任宣传的前崎忙于应对，还担任了电影的监修。在这期间，他每天都奔赴盘面，过着没有休息的日子，患上了抑郁症。前崎在精神科医生的哥哥章（高桥克实）推荐的医院住院。负责医生下令长期休养和当前禁止下棋。将棋极度集中力，只不过是治疗的障碍。身为围棋专业棋手的妻子·茧（内田有纪饰），相信自己能作为同一个赌徒回归，与女儿·春香（南沙良饰）一起，拼命支持着前崎。壮烈的病魔斗争之后，精神恢复了的前崎出院了。另一方面，茧也兼做前崎的康复训练，准备开设象棋围棋教室。开放之日，前崎也被邀请，举行了年轻棋手的对局仪式。看到那个的前崎受到了冲击。完全是异世界的游戏，因为抑郁症而完全无法理解将棋规则。

Sengaki Manabu (Yasuda Ken) is a popular professional shogi player who holds the highest rank of 9-dan. In July 2017, he was in the middle of a game that would determine his rank when his brain suddenly froze. He could not focus on the shogi board and images of death swirled in his mind. As the person in charge of the shogi association’s public relations, he was busy responding to scandals that had shaken up the shogi world. At the same time, he was also a supervising director for a movie on shogi. He had no rest as he would play shogi in the intervals between. His older brother Akira (Takahashi Katsumi) who is a psychiatrist, diagnoses his condition as depression and recommends immediate hospitalisation. The doctor in charge orders Sengaki to take a long rest and stop playing shogi in the meantime. Shogi would only hamper his medical treatment as it entails extreme concentration.
