Kate is a gold medal lawyer at a law firm where she focuses on juvenile delinquency cases. However, a case of abandonment of a baby by a teenage girl made Kate change her attitude towards her career and life. Alison, a high school student, faces charges against children after she left her newborn baby at the bank. But the child's father has never stood up, and the attitude of Alison and her family is even more unpredictable. The attentive Kate discovers the clue and points the finger at Alison's stepfather, Kevin Doyle. Virginia, the biological mother, was finally exhausted and put sleeping pills in Kevin's coffee to end Kevin's life with her own hands. When Virginia approached Kate again to act as her defense lawyer, Kate politely declined because she was going to spend her old age with her elderly father. Due to years of misunderstanding of her father, Kate once deliberately alienated her father, but when all the truth was revealed, she finally understood that her father's love was like a mountain and her family affection was infinite.
