A mortuary worker who collects hair and fingernails from dead bodies begins to kill people to expand his collection, and he sets his sights on Scully. * The concept of a "Death fetishist" was created specifically for the episode, according to Carter, whom originally envisioned Donnie Phaster as a Necrophiliac, but the network did not allow him to use the term or concept as it was deemed too extreme, so it was referred to in a roundabout manner. * This episode is the first of three in which a person can be seen walking towards camera before the screen cuts to black, as happens at the end of this episode's teaser section. The later two examples of this occur at the cliffhanger conclusion of the Season 3 episode "Piper Maru" and, as with this episode, at the end of the teaser section of "Orison", an episode of the seventh season. "Piper Maru" features Alex Krycek approaching the camera and "Orison", also in common with this episode, features Donnie Pfaster doing so.
