Jae-wan, a successful lawyer, takes on the case of a rich executive's son, who has purposely run over and killed a man and left his daughter seriously injured. It's Jae-wan's job to defend a murderer, just another rung on his career's golden-stepped ladder. His younger brother, on the contrary, is a scrupulous and upstanding paediatrician, who always puts the health of his patients over profit and money, often contravening the rules of the private clinic where he works. The brothers meet once a month with their wives for fine dining in expensive restaurants, but when an unexpected situation involving their teenage kids arises, their consciences are questioned and their usual dinner conversation takes an unexpected turn.
