Gold medal lawyer Su Heng, provided by his elder sister who sold her three pieces of gold, discovers only after signing that the accident responsible person is actually his own elder brother-in-law who saved lives with his life! The seventh page of the appraisal report stating insufficient evidence and inability to determine responsibility was pulled away, and his own signature became the blade that killed the brother-in-law. Back then, his elder sister sold her three pieces of gold to support him in studying law, but he personally nailed his brother-in-law into a sinner. Abandoning his law firm future, Su Heng swears to ferret out the true culprit who deleted the page and clear his brother-in-law's name!
