Kim Sang-gyoo

Jeong-eun is dispatched to a subcontracting company. She tries to fit in, but her co-workers aren't comfortable around her and she's completely new to field work. Despite all that, she wants to stay on for a year and then return to headquarters, no matter what. Thanks to a newbie's help, she slowly adjusts to her new workplace.

One day, detective Incheol (Jung Chan) visits Wido. The island is high with hopes for redevelopment as it has been designated as a cultural tourism trial site. Incheol was dispatched to the island to determine the cause of Jong-gu's death who is thought to have been killed in a landslide. But from the first day of his arrival, the islanders' behavior struck Incheol as strange. They wanted him to quietly conclude the case and leave. Incheol, who would even accept dirty money to treat his wife's illness, decides to leave. That night, another case of suicide takes place and Incheol could feel that the residents' bizarre behavior and the series of accidents are not irrelevant. Now, Incheol's investigation reveals the dirty truth the islanders have been hiding.
