70 year old Shen Yanhong (played by Yang Ziqiong) was sent to a nursing home by her son after falling seriously ill, and the house was also rented out by her son. In order to regain her life, she tried to make money but encountered obstacles everywhere. Just as she was about to give up, her talent in the Rubik's Cube was discovered by young Rubik's Cube coach Xiao Wu. One wants to make money and leave the nursing home, while the other wants to save the dying Rubik's Cube training class. The two hit it off and appeared on TV programs. From the beginning, she not only gained fame and fortune, attention, dignity, love, and initiative in life, but also brought vitality to the stagnant nursing home. She was not afraid of failure, fought against aging and prejudice, and arrived at the highest stage of the Rubik's Cube all the way. Finally, with her son's encouragement, she completed an extremely difficult challenge and won the Guinness World Record.
