Wook and his friends now try to live a normal life. Just as he helps a person from a scam for the last time, he 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. 

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.
