At a biotech company called Nugenics, a scientist named Sonny Sanjay has a freakout during a meeting after hearing some high-pitched noises. He locks himself in a laboratory, accesses a computer terminal, and fatally stabs himself in the head when his colleagues try to get him out.
Mulder and Scully arrive to investigate Sanjay's death. The company refuses to give up the hard drive of the computer Sanjay was using before his death, saying it's classified information belonging to the Department of Defense. They also aren't too keen on having the agents visit "The Founder" of the company, one Augustus Goldman.
During the autopsy, Scully finds that Sanjay has written "Founder's Mutation" on his palm. At Sanjay's apartment, the agent's find several files on children with genetic abnormalities. Mulder suffers the same high-pitched noise, which he soon interprets as the words "Find her." The files are quickly confiscated, again on the basis that they're classified by the DoD, and Mulder suspects that the genetic abnormalities might be the result of a DoD experiment.
The agents try to make contact with Goldman through the hospital where Scully works; he agrees to meet with them after Mulder asks him to weigh in on Founder's Mutation. Mulder suspects that Goldman's connections to a hospital that helps destitute young pregnant women might be part of the overarching conspiracy mentioned in the last episode.
Goldman says his company is working to help children who are suffering from several horrific genetic abnormalities. Scully speaks with a young boy named Adam, who was included in Sanjay's files and has been in Goldman's care since he was a baby; she wonders why he hasn't been released, and posits that Goldman might be after some alien DNA. A young pregnant woman from Scully's hospital is run down by a car, and the agents find that her fetus has been surgically removed.
Mulder and Scully find that Goldman's wife, Jackie, has been committed to a mental institution for murdering her child. Jackie recalls how she witnessed her daughter Molly breathing underwater about 10 minutes after falling into a pool. She says was nine months pregnant at the time, and tried to flee. When she got into a car accident, she claims that she experienced the high-pitched noise and cut open her womb to free her son.
The agents realize that a janitor named Kyle Gilligan has been present at the incidents of high-pitched noises, and that he is Goldman and Jackie's son. He says he didn't mean to kill Sanjay, who was trying to help him, but has been working as a janitor at hospitals to try to find his sister. Kyle reunites with Molly, and the siblings quickly focus their powers to disable the agents, kill Goldman, and escape. The DoD quickly takes over Goldman's lab, but Mulder has managed to sneak a vial of Kyle's blood out.
