Return to 20 years old

68-year-old Shen Mengjun’s biggest hobby is square dancing. She feels that she can only regain her youth when dancing. But after experiencing a fraud case, the money Mengjun wanted to buy her daughter's wedding house was in vain. After being depressed and drunk, she woke up and returned to her twenties. She was discovered by music producer Tan Ziming, and she teamed up with her granddaughter Xinran to participate in a music competition. On the one hand, Mengjun wants to help his granddaughter realize her music dream, and on the other hand, she wants to get the bonus to buy her daughter a wedding house, and she has high morale to get through all the obstacles. Mengjun's long-time friend Dahai has always been silently caring and devoted to him, but Mengjun gradually fell in love with Tan Ziming as he spent day and night together, but Mengjun did not have the confidence of young people in love. In the end, in order to save his critically ill daughter, Mengjun resolutely gave up the game and gave up blood transfusion to save her daughter. When Mengjun woke up lying on the blood transfusion bed, she was 68 years old again. Although she was no longer young, she untied the knot between her and her family and understood that even at the age of seventy, she could still live a wonderful life.
