真木（神尾楓珠）の改革で、ＡＩ化による職業の合理化が進む。サチ（山田杏奈）の母で中学教師のタエ（西田尚美）もその対象となる。不要なものは切り捨てる、その政策に、住民の不満が噴出する。真木の支持率は低下し、総理罷免ラインの３０％に近づく。そんな中、母のことで真木への不信感を抱いていたサチは、平（星野源）とともに真木のある秘密を知る。それは、鷲田（柄本明）政権を揺るがしかねない衝撃的な事実であった。
Aran's reforms extend to streamlining of human labor by utilization of AI. Along this line, Sachi's mother Sagawa Tae, a middle school teacher, is designated as a candidate for resignation. The policy of eliminating unnecessary labor meets strong opposition from the residents, lowering Aran's approval rate to near 30%, the threshold for his resignation. Sachi, who has come to distrust Aran over the case of her mother, stumbles upon his secret, as does Kiyoshi, which is one that could cause damage to the Washida Cabinet.
