Lance Reston and a member of the program group called "Grave Encounters" went to an abandoned mental hospital to shoot a show, and "Grave Encounters" is a show that specializes in finding ghosts and other supernatural events. And this program found this mental hospital because it is said that there have been many scientifically unexplainable phenomena in this hospital, and these phenomena have been reported a few years ago, and there has been no definite explanation.
In order to capture valuable TV images, at night, they consciously locked themselves in this horrible building as usual, and began to use cameras to capture some unnatural phenomena. But they soon realized that this building is not just as simple as haunting, this hospital seems to be alive, and they don't plan to let these people leave. They found themselves lost in a weird place like a maze, with only endless corridors and the ghosts of people who died in this hospital before.
They even soon discovered that their sanity was a little unclear, like stepping into a mud, sinking deeper and deeper, unable to extricate themselves, and finally reached a point of madness.
Until finally they found out that if they wanted to escape, they must first understand the dark past of this hospital.
