Kunchiyan plot: According to local legend, Kunchiyan mental hospital was closed in the 1990s because of the bizarre death of patients. It is said that doctors abused patients.

A network radio program recruits brave people to participate in the "horror reality experience show" to explore Kunchiyan, and they will broadcast the haunted house adventure live.

In order to attract more people to watch the live broadcast, the host secretly set a trap. As they go deeper into the restricted area of the hospital, they are getting out of control. Ghosts who died of abuse hide in the shadows and reach out to them.
