on the edge

A close-up of a hand turning a knob on a machine with a label reading "Stängd," followed by a woman's face in profile, then a sign showing a man falling out of a door with the text "Är dörren ordentligt stängd" and "VARNING," and finally a close-up of a knob with a label reading "Öppen." The sequence alternates between the machine controls and the woman's face, with the sign appearing twice, suggesting a looped sequence of a malfunctioning door and a warning.
