The series centers on FBI special agents Fox Mulder (David Duchovny) and Dana Scully (Gillian Anderson), who work on cases linked to the paranormal, called "X-Files". Mulder is a believer in the paranormal; the skeptical Scully was initially assigned to debunk his work, but the two have developed a deep friendship. In this episode, Mulder and Scully investigate the death of a baby born with severe physical defects. Traveling to the small isolated town of Home, Pennsylvania, the pair meet the Peacocks, a family of deformed farmers who have not left their house in a decade. Initially, Mulder suspects the brothers kidnapped and raped a woman to father the child, but the investigation uncovers a long history of incest involving the Peacocks' own mother.
