The video is approximately two minutes and 55 seconds in length. It contains the bold white characters "DNI/27" imposed in the bottom left corner.
A diminutive being that fits the description of that of the Greys is seated at a rectangular table. The subject, which Victor (the voice disguised individual who says he smuggled this tape out of Area 51) says was brought to Area 51 after its craft was shot down in 1989, is situated behind the end of the table farthest from where the video is being shot and is behind a large piece of glass which Victor describes as part of a "bio-containment area" meant to protect the alleged alien from microbes and viruses.
Reflected in the glass is what appears to be two television monitors. The alien's head appears to be covered in bruises and what Morton suggests is a heart monitor can be seen on the table in front of the being.
A person who Victor claims is a military officer attempting to communicate with the alien telepathically can be seen in the left foreground, while a more casually-dressed human figure can alternately be seen entering/leaving the video in the right foreground. The room where the interview is taking place is very dimly lit, so darkness obscures the two and reveals them as nothing more than two unrecognizable shadowy figures. For the same reason, only the creature's head is continuously visible, while brief glimpses of its torso are also shown.
About halfway through the video, the alien becomes visibly distressed and appears to begin suffering from violent spasms and bouts of choking/gagging. The military officer signals for two medics, wearing scrubs and masks, to come to the aid of the convulsing alien. The medics shine a flashlight into its facial orifices, and one begins to wipe foam away from its mouth. At this point the video ends.
