The video tells you about the supposed message in the famous video at the start. It proceeds to play the video forwards and normally. After, it plays the video in reverse. After that, it again is shown backwards but also in slow motion. It tells you to listen VERY closely as they play it even slower. After a while of even slower, Jeff The Killer with an outstretched, toothy grin will pop up with an insane roar that loops.
