A girl joins the student club of paranormal researchers, intrigued by their interest in uncovering the mysteries of the supernatural. Eager to delve into their investigations, the group sets their sights on an infamous village house where a resident hanged herself a few years ago. The house has since become the center of dark rumors among the locals, who speak of an evil ghost that now resides there. The villagers even went so far as to invite a shaman to exorcise the spirit, but tragically, she was found dead shortly after her attempt.

Despite the chilling tales, the students remain skeptical about the existence of ghosts. Driven by curiosity and a desire to challenge their doubts, they decide to visit the cursed house. Their plan is to conduct a ritual to provoke any potential supernatural presence and simultaneously study the effects on the human brain during sleep, particularly when its rhythms fall to 0.0 MHz. They believe that this will provide concrete scientific data, either debunking the myths or providing insights into the human psyche under extreme conditions.

As the night unfolds, the students set up their equipment and prepare for the ritual, each with a mix of anticipation and skepticism. The eerie atmosphere of the house begins to play on their nerves, but they press on, determined to uncover the truth. As they delve deeper into their experiment, the line between reality and the supernatural blurs, leading to unexpected and terrifying consequences. The group’s journey into the heart of the paranormal becomes a test of their courage and beliefs, revealing that some legends might hold more truth than they ever imagined.
