Choi Joon Woong seeks a job, but it's hard for him to get hired. One night, he witnesses a man trying to end his life and decides to stop him. He gets acquainted with grim reapers Koo Ryeon and Im Ryoong Gu, who belong to a crisis management team. Their purpose is to prevent people from committing suicide. After Joon Woong ends up in a coma and becomes half-human and half-spirit, he is employed by a company of grim reapers as the newest member of the crisis management team.

A devoted wife and mother, Soon-ok suddenly learns that she has a terminal illness and is given less than a year to live. She pauses to think about the family she will leave behind: a completely helpless husband, a kind son who cares about nothing except his mother, and a daughter too busy to attend to anything but her own affairs. Soon-ok begins to prepare a gift for her family -- the opportunity to bring them together for a final farewell. Once fractured and separated, the family comes to learn that death does not have to be the antithesis of life, but can be its affirmation and awakening.
