The Video
A brief disclaimer is shown before the footage starts, stating that the video is shocking. The actual footage starts with the camera panning from a house to a group of electrical wires, where it continues panning. Already it's quite clear something's fishy, but the kicker is at the very end, where a scary alien pops up wiggling its head and screaming in a distorted voice.
