After attempting to save a man from killing himself by jumping into the Han River, Junwoong (Rowoon) ends up in a coma. Since then, he has gotten a chance to work as a grim reaper in the Risk Management Team with Koo Ryeon (Kim Hee Sun).

Unlike other grim reapers who collect the souls of dead people, the Risk Management Team is the one who saves people who try to end their lives. The people Koo Ryeon, Junwoong, and the team try to help include victims of bullying, sexual harassment, depression patients, and even criminals.
