A dizzying world of hard-at-work grim reapers and an extraordinary offer await Choi Jun-woong after a freak accident lands his body in a coma.

While trying to help a TV writer tormented by the return of her high school bully, Jun-woong fails to follow Koo Ryeon's orders to rein in his emotions.

Jun-woong officially joins Ryeon's team. When his best friend needs saving, he travels back in time and gets a glimpse into a tough childhood.

The team sets out to convince both father and son, in the past and present, to rethink their decisions. A runaway soul tells Jun-woong her story.

The runaway soul refuses to move on until her husband stops blaming himself for her death. As other reapers come after her, Ryeon's team holds them off.

One day before his death, a war veteran rediscovers the meaning of life as he recounts his journey to Ryeon, Jun-woong and Lim Ryung-gu.

The next case surfaces at a cosmetics company. When their tech breaks down, the team uses their observation skills to narrow down the at-risk human.

Unable to ignore the discovery of an online scammer who is enabling people to end their lives, Jun-woong takes matters into his own hands.

An urgent alert leads the grim reapers to an atypical case involving a dog that's been separated from his longtime owner.

A woman who was sexually assaulted grapples with trauma, while her twin brother seeks justice. The case proves personal for Ryung-gu.

After hearing an awful rumor about Ryung-gu, Jun-woong learns the tragic truth behind his colleague's past, and how he came to be a grim reaper.

A familiar face comes up on the team's radar, but her negative energy levels seem to fluctuate irregularly. When Ryung-gu finds out, he steps in.

Mutual grief over the pain suffered by a long-lost friend brings two women together. The story of the comfort women and the horrors they endured is told.

The sorrows of Ryeon's past come to light. Centuries ago, she was a highborn lady who was left with deep scars after surviving a harrowing event.

Helping a tormented top star is an especially important case for Ryeon. Meanwhile, Park Jung-gil demands answers about the secrets being kept from him.
