After an ancient statue of the Buddha was excavated in Jinyang-gun, strange things start to happen. The people in Jinyang-gun see the black rain coming down from the sky. Archaeologist Ki Hoon believes that all the incidents come from the statue of the Buddha. Also, he thinks that the statue is cursed. Ki Hoon's wife, who is living in Jinyang-gun, happens to see the statue of the Buddha being exhibited in the county office. 

Do Kyung is forced to go to Jinyang-gun county office for voluntary work. At the county office, there are the governor and citizens gathered to have a discussion about the black rain and come up with a solution for those who are suffering from the damage by the black rain. Yong Ju, who bullies Do Kyung, also comes to the county office. However, people suddenly start to go mad and violent, and chaos is brought to the county office.

Those who survived the violence and fight lock the entrance to the county office. Yong Ju suggests that this chaos came from those who got infected by the virus in the black rain. He adds that anyone who got the black rain should be removed. In the meantime, Ki Hoon and Seok Hee are blocked by the army from going into Jinyang-gun.
