0.0 MHz (horror movie: trailer).
Here’s the trailer for the South Korean horror flick, 0.0 MHz, where the staff of a supernatural exploration society enter a haunted house with a lifesize female doll and use technology (the 0.0 MHz frequency) to encourage evil spirits to possess the doll and bring it to terrible life.
Gee, that sounds like a very bad idea.
Based on the comic of the same name by Jang Jak.
