One day the citizens of South Park wake up to find the internet is gone. When Randy hears there may still be some internet out in California, he packs up his family and heads west.
Stan, Shelly, and Randy Marsh are all eager to get back on the internet after being forced to go to bed the night before by Sharon. As they switch their computers on and load the internet they receive a message telling them their internet is not working.
Going to the Broflovski's house, Gerald and Sheila welcome them in, alarmed that the Marshes have no internet. Trying to get on to Kyle's, Stan discovers that it has no internet either.
After everyone in town discovers they have no internet, it becomes almost nationwide, with even the television broadcasters unable to deliver any news because there is no internet. It is soon discovered that somewhere near California still has internet, so Randy gathers his family and they head westwards. Shelly is desperate to get back online to talk to her boyfriend Amir, who she speaks to only with e-mail, and punches Stan every time he tries to comfort her.
Arriving at the camp, they are all given tickets and told to wait for their number to come up so they can use the internet. It turns out that only forty seconds is allowed for each person. Knowing he cannot watch porn in such a short time period, and most certainly not in front of everyone, Randy sneaks into the room where the internet is hidden and uses the internet to watch unusual pornographic material such as content containing zoophilia and emetophilia. After people outside (including the camp wardens) hear Randy's incredibly loud moaning during masturbation, they break in to find Randy, and most of the room, covered in his own semen. Randy blames it on a ghost and claims he is covered in ectoplasm. However, what he did also used up the little internet that was left.
At Kyle's home, the Broflovskis are all watching the news. The news (only able to report on the state of the internet) shows scientists trying to communicate with the internet, which is portrayed as a giant Linksys-style wireless router in an underground cave. When Kyle sees the internet, he realizes what the problem is.
After arriving at the internet, Kyle is said to be the last hope. Kyle walks up to the internet and pulls out the giant plug from the wall socket, waits several seconds, then plugs it back in. The internet immediately becomes functional again.
Back at the camp site, where everyone is celebrating the return of the internet, Shelly's eager to start mailing Amir again when a boy behind her hears the name and he turns out to be Amir. Shelly and Amir exchange a few awkward sentences and are unable to face each other. Amir walks away with the promise to e-mail her, and Shelly returns to hugging the computer, eager to talk to Amir online again.
Randy later gives a speech that the internet is not to be taken for granted and people should not "over log-in", and that porn should only be viewed a maximum of twice per day.
