Is it better to live forever or to finally be able to die?  Kim Shin (Gong Yoo) is a decorated military general during the Goryeo Dynasty who is betrayed by the jealous king he served. When Kim Shin is faced with death instead of honor after fighting a mighty battle, God turns Kim Shin into a goblin instead, tasked with protecting certain people from a life of misery. But immortality is wearing on Kim Shin, and he longs to find the prophesied human bride who can set his soul free. Kim Shin becomes accidental roommates with Wang Yeo (Lee Dong Wook), the grim reaper who ushers people’s souls into the afterlife.

Kim Shin’s nephew, Yoo Deok Hwa (Yook Sung Jae), is a rebellious chaebol heir whose family has been caretakers of the goblin for many generations. Ji Eun Tak (Kim Go Eun) is a high school senior whose mother was saved from an accident by Kim Shin 19 years ago, and ever since then she has been able to communicate with dead people. Sunny (Yoo In Na), the owner of a chicken restaurant and Eun Tak’s boss, crosses paths with Wang Yeo and becomes smitten with him. Can Eun Tak be the true “goblin bride” with the power to release Kim Shin from his eternal misery?
