Once Wook realizes what Duon Village actually is, he receives a big shock. None of the police takes him seriously when he tells them about the village, and they seem to think he is Ha Neul’s kidnapper. Meanwhile, the gangsters who abducted him keep showing up, so Wook goes back to see Pan Seok.

A village holds spirits of missing, deceased people. A search to find the missing bodies and discover the truth behind their disappearance occurs.

Wook continues to stay with Pan Seok, the man who lives in Duon Village and finds the villagers’ missing bodies. When Wook meets Yeo Na in the village, he realizes that she was the girl he witnessed being abducted. Meanwhile, Jun Ho finds Yeo Na and Nam Guk’s phone numbers in the call history of a murder victim and becomes worried.

Wook is despondent over Nam Guk’s death, but he soon begins to track down the mysterious thugs who kept following him. Jun Ho also continues his investigation on the deaths of Nam Guk and Jang Myung Gyu, as well as Yeo Na’s disappearance. Meanwhile, the sex offender in Duon Village terrorizes the villagers.

Wook discovers that one of the villagers of Duon Village, Kim Hyun Mi, is his mom. Seeing her after all these years makes him feel quite flustered. In the meantime, Wook and Pan Seok must find Woo Il Suk’s body to make sure Duon Village is safe again. Meanwhile, Jun Ho finds a lead to finding Yeo Na.

Wook finds out that his mom worked as a housekeeper for Chairwoman Han of Choiseung Construction. He goes to speak to the chairwoman and runs into Jun Ho. Wook finally tells Jun Ho that he witnessed Yeo Na’s abduction. Meanwhile, Duon Village prepares for their annual Memory Day, and Thomas’ surprise for Yeo Na is revealed.

Pan Seok finds out that Hyun Mi is Wook’s mom. Knowing how painful it is to lose a family member, Pan Seok decides to help solve the mystery of Hyun Mi’s death. Wook, Pan Seok, and Jong Ah plan to sneak into Choiseung Construction to get some answers. Meanwhile, Yeo Na finds a building in the village where she hears strange noises.

Hwang Du Cheol, the man in the derelict building, claims that Thomas had him locked up for years. The village is in an uproar when they find out Thomas’ secret. Meanwhile, Jun Ho gets a phone call from a witness who says he saw Yeo Na. As Wook, Jong Ah, and Pan Seok set out to find some evidence, Manager Wang has them tailed.

Wook goes to save Jong Ah from Manager Wang’s men and ends up recovering a deeply buried memory from his childhood. Jun Ho and the Missing Persons Squad go to meet the mysterious man who says he knows Yeo Na’s whereabouts. Meanwhile, Pan Seok hands Il Du Hyun Ji’s backpack to search for evidence with current technology.

Jun Ho goes to the mountain in Duon Village and says everything he wanted to say to Yeo Na. Then, he joins Wook, Jong Ah, and Pan Seok to investigate the case from 27 years ago. Meanwhile, Thomas finishes his surprise present for Jang Mi as the Missing Persons Squad tracks down Jang Mi’s murderer.

Wook shows up to the shareholders meeting as Chairwoman Han’s grandson, making the culprit fly into a rage. Meanwhile, Pan Seok gets a phone call saying that his daughter’s kidnapper has been identified. Later on, Chairwoman Han is kidnapped and Wook rushes to save her.

Wook is in shock to find out that it was his fault that his mom died. He goes to Hyun Mi and says what he wanted to say to her since her disappearance. Meanwhile, Jun Ho uncovers everything that Lee Dong Min has done and searches for Yeo Na’s body. With the case coming to a close, Wook asks Thomas about how he died.

Wook and his friends now try to live a normal life. Just as he helps a person from a scam for the last time, it becomes involved in a kidnap and murder case. Regardless, he looks the other way and plans to focus on his own life. However, a ghost appears before him. Ever since Duon, he has never seen a single ghost until now.

The Industrial Complex Three welcomes Wook and Pan Seok. It turns out Hyun Ji had been living in the village until Pan Seok found her remains. Also, they find that Yang Eun Hee is a resident there. For Myung Ja’s sake, they decide to find who killed Eun Hee and secure her body so that she may rest in peace.

As soon as Eun Hee’s case is resolved, Wook heads to prison to visit Lee Dong Min. There, he runs into two men he was least expecting to see. Jun Ho continues his search for Se Young and looks after Bo Ra who is left all alone. Meanwhile, a high school boy suddenly appears at Industrial Complex Three, asking to save his sister who is in danger.

Bo Ra comes to find Wook and claims that he is her father. Wook is flustered by the news, but he let her stay at his place as she has nowhere else to go. Pan Seok decides to stay in Industrial Complex Three, hoping to find more traces of Hyun Ji. While there, he learns more about Mr. Jung, the headmaster, and how he died.

The Goliath is about to make a huge drug deal. Just before the exchange is made, Gwang Taek finds out that Sang Chul is an informant for the police and kills him. He also finds out that Se Young is still alive and tries to find her to cut loose ends. As Sang Chul wakes up at Industrial Complex Three, Wook investigates him to find Se Young before she gets killed.

Alice is found on a big boat in the middle of the woods soon after she goes missing. Although everyone doesn’t know what the boat is, Captain Kang seems to know something about it. Meanwhile, further investigation on Se Young’s case leads to new information. According to her testimony, the police might have a lead on who the Goliath is.

Wook learns from Il Yong that the Goliath is a man named Pil Joong. He is Il Yong’s friend and also the person who murdered him. Meanwhile, the investigation on finding Ro Ha’s body continues. With new evidence from a new witness and help from Ro Ha’s drawings, the police and Pan Seok are able to narrow down where he could be.

Se Young is now discharged and free to go out. Bo Ra takes Wook and Se Young out for a meal as a family for the first time. Meanwhile, another incident happens at the Industrial Complex. Ha Yoon suddenly becomes missing and Captain Kang knows who the culprit is. She asks Sang Chul to take care of it quietly, but the case becomes bigger.

The whole village finds out that Il Yong is able to go over to the world of the living. Although everyone knows that it is wrong to ask him many favors, they are still curious about their families. Meanwhile, a new threat comes over from China. It seems that the Goliath is not the brains of the drug ring.

Pil Joong manages to get away from Wook and meets his boss. However, after the meetup, Pil Joong’s car mysteriously crashes into a tree and kills him. Meanwhile, Gwang Taek hands over where Sang Chul’s body is after he hears the death of the Goliath. Thanks to Detective Shin, Sang Chul is found and allows him to rest in peace.

Jong A, Wook, and Pan Seok set up an operation to catch Gun Ju red-handed. However, something goes wrong and puts Pan Seok in danger. Meanwhile, Young Jin tells Eun Sil the truth behind his death. He tells the incident he had with his son and reveals the true reason why he wants nobody to find his body.

Wook and Il Yong find a house that Il Yong cannot enter. Apparently, the owner of the house is the lady who has been appearing in Wook’s dreams. Meanwhile, the search for Alice’s body leads to a clue that her father is an abusive man and that he fled to Guam. Pan Seok and Jong A try their best to track him down and find Alice.

Wook finally finds Il Yong. But it seems he is not the only one who needs to find him. Although Wook is happy to find Il Yong, his ill-fated relationship with Yoon Gu begins. Meanwhile, Jong A and Pan Seok are on the verge of finding Eun Sil’s body. They uncover what actually happened on the day Eun Sil died.
