Yiyu Island

Xuan Woo-hyun was looking for a place called "Iniyu Island" near Jeju Island and recalled a past event four years ago. At that time, he was still the head of the planning department of a travel agency, and he specifically planned to go to Yiyu Island to carry out promotional work in order to build a tourist hotel called "Imiyu Island". On the ship sailing to Yiyu Island, Jeju News Agency reporter Qian Nanshuo tried to stop Xuan Yuxian's trip, asking him to turn the ship around, and claimed that only dying people could see Yiyu Island, but Xuan Yuxian disagreed. That night, Qian Nanshuo disappeared on the boat, and Xuan Yuxian was suspected of murder. After investigating the details, although Xuan Yuxian was acquitted due to insufficient evidence, he was still troubled by various problems, so he decided to go to Jeju Island with the newspaper editor who concluded that he was a murderer to find the truth about Qian Nanshuo's disappearance. With in-depth contact with the islanders, Qian Nanshuo's past actions were revealed one by one, and the rumors on the island that Qian Nanshuo's family was cursed by the sea monster are getting closer and closer to the two visitors...
