Original: 딜리버리맨
A meticulous young man co-launches a taxi service for spirits with a ghost who can’t remember how she died. Will the duo find love – even though one of them is dead?
A ghost gets in Young Min's taxi, and she can't leave it for an inexplicable reason. What's worse is that Young Min learns that the house he's living in with his grandma will get auctioned off if he doesn't pay the mortgage. Luckily, Ji Hyun, the ghost, has an idea to help him make the money he needs to save his house.
The plan to make money for the mortgage goes to waste, and Young Min is upset about it. Ji Hyun persuades Young Min to help Byung Chul, and they decide to help Byung Chul and his wife So Yeon. So Yeon was about to receive compensation money from Byung Chul’s company, but a woman who claims to be Byung Chul’s mother appears. Young Min gets suspicious about the woman’s identity.
Young-min notices that the hairband on Ji-hyun's wrist is his late mother's. However, Ji-hyun doesn't remember anything about it or why she has it. Making things more confusing are the pictures of Ji-hyun and his mother together before the accident found on his mother's phone. Meanwhile, the police call Young-hin in for questioning about his mother's death, suspecting him of his involvement.
Now that Ji-hyun is gone, Young-min makes some decent money. However, something inside him longs for her return, and he finds a way to charge the cell phone to bring her back. When Ji-hyun returns, they run into the Jayu-ro ghost, who points them to a popular ghost location. Meanwhile, the police think the hit-and-run case and Ji-hyun's incident are related.
Young-min can't stand the thought of Ji-hyun leaving him. When Young-min takes her to see Sin-woo to fulfill his contract, he changes his mind. Meanwhile, a young boy gets in Young-min's taxi and asks for Young-min to grant his wish.
Ji-hyun sticks to Ga-eun to find Ha-yul, the young girl who had gone missing. Young-min doesn't give up after fighting off a bunch of thugs and manages to convince Ga-eun to tell him the truth. Meanwhile, as Young-min fulfills Ji-hyun's wishes one at a time, he conveys his feelings for her.
On the first date with Ji-hyun, Young-min wonders why the rule of ascending to the sky doesn't apply to Ji-hyun, and that offends her. Young-min and Ji-hyun help find Doo-kang’s daughter. In return, he provides information on Nurse Kim Jung-woo. Ji-hyun and Young-min head to the studio apartment building where a faceless ghost appears, and they run into her.
Young-min gets caught while coming out of Kim Jung-woo’s studio and gets arrested for trespassing. After finding out that Kang Hyung-soo is Ji-hyun’s dad, Young-min asks him how she died. Meanwhile, Eun-soo’s mother falls and hurts herself. Gyu-jin treats her, but something goes wrong with her.
Gyu-jin drops by Young-min's house to see if Young-min has found any evidence. He finds out that Young-min has no solid evidence to back up his suspicion. Meanwhile, Young-min finds the note that Nurse Kim Hee-yeon left Jung-woo, so he confronts her. On the way home, Young-min gets attacked from behind and kidnapped.
Young-min gets saved by Ji-hyun and escapes from the fire. Young-min reports to the police that all the murders were done by Do Gyu-jin. After a police investigation, Gyu-jin flees, and Young-min finds out his hiding spot. When Young-min confronts him, Gyu-jin threatens to destroy the most important piece of evidence.
Kim Hee-yeon makes a false statement and claims that she’s responsible for all the murders that happened at Deahun Medical Center. Gyu-jin learns that Ji-hyun is still alive and that she was transferred to his hospital. When he’s about to inject a drug to kill Ji-hyun again, Young-min jumps in and catches him in the act.
