saw this awhile back. If i remember correctly its an investigation into whther or not a video of an interview with an alien is real or not. they investigate prop and puppet experts, etc. According to the video, the alien crash landed and was dying and could only speak telepathicaly to the narrator who intern explains what the alien is saying and doing. Also the alien says that they eliminated all harmful bacteria form their planet 50 years ago and that he is dying from a lung infection since its immune system is so weak.
