Shen Xiaohe, a professional dog trainer, is hired as a substitute mother by the Gu family because she looks identical to wealthy president Su Lingwei. With firm methods like training dogs, she guides the three misguided children: saves the eldest son from a deceptive girlfriend, wakes up the gullible second son, and stands up for their youngest daughter bullied at school. While exposing the villainous Wen Jinglan and her daughter and resolving crises in the Gu family, Shen Xiaohe builds deep bonds with the kids. She helps Su Lingwei divorce Gu Cheng, brings the wrongdoers to justice, and the whole family embraces a new happy life.
