0.0 MHz is a 2019 South Korean supernatural horror film written and directed by Yoo Sun-dong and starring Choi Yoon-young, Shin Joo-hwan, and Jung Eun-ji.

[2][3] The film is based on webcomic of the same name by Jang Jak initially published in 2012.

[4] A girl joins the student club of paranormal researchers, and the group goes to an infamous village house in which a resident hanged herself a few years ago.

The villagers even invited a shaman to drive away the spirit, but that woman was found dead.

Not particularly believing in ghosts, the students come to the cursed house to conduct a ritual there and check what happens to the human brain during sleep, when its rhythms fall to 0.0 MHz.
