In the 1980s, in Liuhé Town, Zhou Xiuyun was planning to send her youngest granddaughter away. During an argument, she accidentally collapsed. When she woke up again, she had been taken over by a modern-day special agent who had traveled through time. Her son-in-law had died, her daughter had disappeared, and the Huang family had abandoned her three grandchildren. Her son and daughter-in-law only wanted to get rid of the burden. Determined to protect the three children, she relies on her cooking skills to set up a street stall selling wontons and braised delicacies, struggling to make ends meet while repeatedly standing up to harassment from her son, the Huang family, and others. When several forces join together to forcibly take the children away, her daughter, who has been missing for three years, returns with evidence. Zhou Xiuyun resolves to settle old scores with her enemies.
