Mulder, who has come to doubt that alien abductions are anything but a terrestrial cover-up, meets Cassandra Spender, a multiple abductee, and her son Jeffrey, an FBI agent.
Meanwhile, the Syndicate is having some trouble with the arrival of some very real aliens.
This episode contains examples of:
- Myth Arc
- A Riddle Wrapped in a Mystery Inside an Enigma: A variant on the trope phrasing. Agent Mulder, who has grown skeptical of the existence of extraterrestrials but instead believes the alien conspiracy to be a lie concocted by the military to hide a different and all the more sinister scheme, describes his belief in "a conspiracy wrapped in a plot inside a government agenda."
- The Skeptic: Mulder in this case, who believes Cassandra Spender was not abducted by aliens (though ironically, she came forward with the story after being inspired by Mulder himself).
- Would Hurt a Child: Krycek tortures an unfortunate kid in a gulag and has him infected with the Black Oil.
