In the novel, Stu Redman is taken to the Stovington CDC facility after their complex in Atlanta is compromised by the superflu. In the TV miniseries, Stu is taken directly to Vermont. In either case, the CDC staff were baffled and mystified by Stu Redman's total immunity to "Captain Trips" and all of their efforts to discover how he is immune or replicate this immunity in a vaccine or cure ended in complete failure.
Obsessed with the idea of keeping the secret of what they have done- extensively violating both the spirit and letter of the United States Constitution and its accompanying Bill of Rights, for a start- surviving CDC staff, federal agents, and United States Army personnel held onto the Stovington CDC facility until the bitter end. Eventually, having run out of uses for Stu Redman and knowing that time is short, the surviving authorities in the facility's chain of command order that Stu be killed. In the novel, an "Army equivalent of a Mafia button man" called "Elder" arrives to kill Stu, while in the miniseries, Dr. Richard Deitz spitefully decides to kill Stu on his own.
Stu fought and killed his attacker, then escaped. Later, when Harold Lauder's stubborn distrust of Stu forced a small group of survivors to make the trip to Stovington, Stu was visibly alarmed by seeing the facility again and absolutely refused to go inside. Glen Bateman, Harold Lauder, and Frannie Goldsmith went inside anyway, finding a silent place that smelled of death. Power was still supplied to the facility from some source, as the three used an elevator to go up to the 2nd and then the 3rd floor. The 2nd floor was largely offices and only a few dead bodies were found there, but many more lay around the 3rd floor, which was set up like a hospital but with airlocks instead of standard doors.
Frannie Goldsmith noted there were "very few women" among the dead, making her wonder if some attempt had been made to evacuate them before the end. Regardless, the Stovington CDC facility was deemed "a dead place" and none of the visiting group had any desire to stay. They soon departed, leaving the abandoned complex to be slowly reclaimed by the elements.
