The police find a burnt body in an abandoned mansion in the middle of the Radvaň housing estate in Banská Bystrica. Student Jana has a feeling that it is her ex, whom she has not been able to reach after the holidays. Moreover, she sees strange shadows in the window of the mansion at night. Her roommate, film student Elena, goes to the mansion with Kamil and a camera to investigate further. Strange noises are heard in the mansion, and for inexplicable reasons something falls next to them. This convinces them to investigate the mansion more seriously. Jana and four roommates from the mansion, equipped with cameras and walkie-talkies, occupy the mansion for the night in order to focus on special camera phenomena. Little do they know that what they will face in the next few hours will be beyond their understanding and their own existence. The situation gets out of control and it seems that the only evidence of the events of that evening is found on the camera recordings.
