Modern daughter Lin Wanxing was reborn in 1975 due to a knot in her heart and an accident, but her soul was imprisoned in the body of her father, the 18-year-old educated youth Lin Chaoyang, who had been a lifelong quarrel and eventually left home. In order to reverse the family tragedy, she must assume her father's identity and live a new life for him: to make up for the harm she caused to her mother, to protect her dreams, and to find out the truth that led to her father's decadent life. In this process, she truly understood her parents' love and pain, and also healed her own inner trauma.
