An international group of film students finds a disturbing video clip on the dark web which seems to contain poltergeist phenomena. Agreed that it's just what they need for their latest documentary project the group travels to the sanatorium shown in the video clip. Once there, they rig up their camera equipment and start to explore the possible ghost activities - until the true horror begins. 　　译文(2): 一个国际电影学生组织在暗网上发现了一个令人不安的视频片段，似乎包含了恶作剧的鬼怪现象。他们同意这正是他们最新的纪录片项目所需要的视频剪辑中显示的团队旅行到疗养院。一旦到了那里，他们装备好摄像设备，开始探索可能的幽灵活动——直到真正的恐怖开始。
