In the related video, a woman and her partner are going to take the elevator. The woman enters the elevator first, but the bottom of the elevator is empty, so the woman falls down in an instant. The next second the camera switches to the stage. It turns out that the elevator shaft is connected with the wet slide on the stage. The woman slides down the slide all the way to the front of the stage.
In the video, the woman's frightened facial expression reveals her inner fear.
