Gao Zhishu (Park Jin-hee), who grew up in the countryside, has a not-so-happy childhood memory. In her memory, her disabled father was an alcoholic and would be violent to her mother (Kim Hae-sook) when drunk. What her mother didn't expect was that when she grew up, Zhishu, who had been determined to be a failure since childhood, became a writer and even married to the metropolis of Seoul. In this way, mother and daughter began the longest separation in their lives. Five years passed in a blink of an eye, and Zhishu also became a mother. It was not until then that she realized how much effort her mother had put in to raise her. In order to fulfill her filial piety, Zhishu returned to her long-lost hometown without saying hello. In the faint sadness and faint uneasiness, the mother and daughter began a "close contact" for three days and two nights. During this time, can Zhishu repair the long-standing indifferent family relationship between her and her mother?
