A car accident brought a devastating blow to the families of the sisters Xiufang (played by Xu Di) and Xiuli (played by Chen Xiaoyi) - the elder sister Xiufang's only daughter Anxin (played by Zhong Chuxi) is a young dance teacher who was seriously injured in the car accident and lost both legs; the younger sister Xiuli's youngest son unfortunately died but the eldest daughter Ruohua (played by Yang Chaoyue) escaped. Anxin, who regards dance as her life, can't bear this huge blow. She is discouraged and depressed. Her husband Qin Feng also gradually retreats and wants to escape from the marriage. Xiufang, who has been obese for most of her life, is determined to inspire her daughter's confidence in life by completing the weight loss that she has never insisted on; Ruohua takes her mother to live in the university dormitory to help her mother out of the pain, but Xiuli, who is heartbroken, can't restrain her desire to control, and Ruohua, who is in love, is tortured by her mother's excessive pressure. With Xiufang's firm company, Anxin bravely walked out of her marriage, and with the company of her dance partner and lover Lin Tianyu (Hou Wenyuan), she finally returned to the stage after overcoming many difficulties. Ruohua became paranoid in her confrontation with Xiuli, but in the end, the mother and daughter untied their knots and faced life anew.
