Chairwoman Li Shengqing fell out with her daughter over a disagreement, missing their final chance to reunite. After her daughter passed away, she gave her granddaughter 500,000 yuan every month. But at a birthday banquet, she discovered that Shen Mingyue, the girl serving dishes and gnawing on cold steamed buns, was actually her biological granddaughter. As the investigation deepened, the conspiracy behind her daughter's car accident gradually came to light. Li Shengqing cleared Mingyue's name, exposed the impostor's family, recovered the stolen assets, and brought the perpetrators to justice. After ten years of mistakenly doting on the wrong granddaughter, the grandmother and granddaughter finally reunited and joined hands to rebuild their family.
