**Title:** (Implied) The Terrifying Case of a Kidnapped Child and the Dark Reality of Sadists
**Summary:**
* The narrator sets the tone by distinguishing between serial killers (those who kill three or more people over time) and the public's misconceived notion of them, highlighting that true sadists are more frightening.
* A case in Anchorage, Alaska, is introduced, where a mother's worst nightmare unfolds when her young daughter (around 10 years old) vanishes during a game of hide-and-seek in a dog park in 2017.
* Despite an extensive search, no body or ransom note was found, leaving the case unresolved.
* The story jumps to 2022, where the same mother, now with a new baby, receives a mysterious envelope containing a generic USB drive.
* The USB drive holds a disturbing video of her kidnapped daughter, now apparently malnourished, blind, and being led through a sewer-like environment by an unseen presence.
* The daughter is revealed to still be alive, and the search for her continues.
* The narrator reiterates the initial point, emphasizing that while serial killers are feared, it's the sadistic acts of individuals like the one in the video that are truly terrifying.
