Mulder and Scully's investigation into a mass shooting in a coffee shop leads them to believe that the targets were not the low level drug dealers and wholesalers who were killed but rather Donald Geldman who had been sitting at a table working on his laptop computer. The Lone Gunmen tell Mulder and Scully that Geldman was one of the original computer geniuses who disappeared years before. His laptop leads the agents to a hacker, Esther Nairn, who goes by the name Invisigoth. She tells them of a vast government conspiracy involving artificial intelligence that allows them to see everything and take action against all enemies. Written by garykmcd

And you thought C.O.S. was nasty.
9 November 2006 | by (Washington Terrace, Utah) – See all my reviews

Kill Switch re-visits the idea of artificial intelligence(AI) gone rogue, a concept first explored in season one's "Ghost in the Machine". Computer stuff always fascinates me, so it's easy for me to like episodes with this subject matter. It's interesting, that right after the teaser, Mulder and Scully come upon Donald Gelman's laptop which still has command on the screen to hit "enter" to initiate program. If only Mulder had known, a big mess could have been avoided, if he had pressed that button. It's funny to see Scully's complete disbelief in AI. Her skepticism is to the extreme in this episode. The Lone Gunmen are featured in Kill Switch, which is always a bonus. Mulder's "virtual" experience is quite entertaining, especially when we get to see "Kung-Fu Scully". She kicks some nurse butt. A little nitpick with a continuity error: Scully and Esther are walking through the woods and you can see snow falling behind them. Two seconds later, they come up to the camper and there is no snow anywhere and not even falling. It's not a negative thing, just a cool nitpick. I actually find some of the AI stuff harder to believe than the paranormal happenings that the agents normally investigate. Kill Switch is a cool, fun, and interesting episode that shouldn't be missed.
