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.
