Synopsis

As Mulder and Scully delve into the link between the disappearance of several teenagers and a secluded religious cult in the countryside, they uncover a disturbing secret: the children are subjected to clandestine experiments. These involve alien DNA, specifically the "Purity Control" strain detailed in the recovered documents from 'The Erlenmeyer Flask.' This discovery leads Mulder down a path, ultimately pointing him toward the man with the crew cut – the killer of Deep Throat.
