While uploading a video he made to YouTube, a man notices his computer has been logged into a strange account with an odd name: NULL. There is one video; he watches it and makes a response, asking whoever is behind it to stop. They don’t listen, and bizarre videos keep popping up, with strange codes and messages that he can't understand. Solve codes, translate sentences, examine images, and help make sense of this channel that someone has made just for him.
