Although he came from a low-income family and attended a non-prestigious university, Lee Han Yeong ardently desired to rise through the ranks of the judiciary. When he married the daughter of the CEO of the Haenal law firm, he also began working with her father, using his position as a judge to benefit the firm. However, as the years passed, Han Yeong’s guilty conscience grew stronger, and he eventually defied his orders, sentencing to life imprisonment for a corrupt president, just to see Han Yeong himself die. Miraculously, he wakes up and finds himself ten years in the past with all his memories intact, and realizes he has been given a second chance to set things right. With the help of Prosecutor Kim Jin A, Han Yeong is determined to seek justice, even in the most difficult moments.
