Lawyer Shen Zhao overturned the case on behalf of his father, but his biological mother Zhou Suyun forced her to withdraw the case because of her family's reputation. After the court broke up, she faced the judicial shady alone, but unexpectedly uncovered the ironclad evidence of her mother's dereliction of duty. Prosecutor Chen Yan's ambiguous support, reporter Qi Heng's fatal clues, and intern Su Yue's betrayal make every step a walk on thin ice. However, retired judge Lin Qiuhe, who was suffering from dementia, repeatedly read out the date, which turned out to be the only password in the whole case. When the blood relationship between mother and daughter becomes the only bargaining chip in the trial, Shen Zhao must tear apart the truth with his own hands between justice and family love.
