The episode opens in 1989, where a creepy doctor, Joe Ridley, is doing some sort of experiment on a man named John Barnett. In the present day, a jewelry store robbery includes a written message from Barnett to Mulder. It turns out Mulder helped put Barnett away for armored car thefts and the murders of two men, but supposedly died in prison in 1989. At his trial, Barnett threatens that he'll get Mulder.
Barnett begins toying with Mulder. A prisoner tells the agents how he witnessed Ridley's operation. Mulder and Scully find that the Ridley was experimenting with sufferers of progeria, a rare genetic disease which rapidly ages children, to find anti-aging techniques. Mulder theorizes that Ridley was using prisoners to experiment on, and that Barnett might be using his youth as a disguise.
Ridley meets with the agents and tells them that the U.S. government sponsored him after he lost his medical license. Deep Throat tells Mulder that the government is trying to bargain with Barnett to get the research he stole from Ridley. Scully finds that Barnett has been in her apartment, and the FBI stakes out a cello recital that was mentioned on her answering machine. Barnett takes a cello player hostage, but Mulder manages to shoot and kill him. He and Scully ponder what become of the research, and the episode ends with a shot of a rental locker at an airport.
Robin Mossley, who plays Dr. Joe Ridley, was recycled as a doctor for three other X-Files episodes. Merrilyn Gann, the prosecuting attorney at Barnett's trial, played Rose Abbott on Everwood.
