“Longlegs” is a 2024 occult serial-killer horror movie about an FBI agent hunting a Satanic murderer whose crimes turn out to be terrifyingly connected to her own past. It mixes FBI procedural investigation with supernatural and demonic elements rather than being a straight crime thriller.

Core story (no-frills)

  • The film follows Lee Harker, a gifted but socially withdrawn young FBI agent in 1990s Oregon who seems to have a kind of clairvoyant intuition for crimes.
  • She is assigned to a decades‑long case involving “birthday murders,” where seemingly ordinary fathers suddenly massacre their whole families and then kill themselves.
  • At each scene there are bizarre, coded letters signed “Longlegs,” filled with occult symbolism and cryptic messages that no one has been able to fully decipher.

Who/what “Longlegs” is

  • Longlegs is the nickname for a reclusive, almost mythic serial killer who styles himself as a servant of a demonic figure he calls “the man downstairs.”
  • He does not usually kill people directly; instead, he uses Satanic rituals, dolls, and psychological manipulation to push parents into slaughtering their own families on or around a child’s ninth birthday.
  • His messages and behavior echo real‑world Zodiac‑style killers, including misspelled coded letters and taunting clues to law enforcement.

The deeper twist

  • As Lee digs into the case, she uncovers disturbing evidence that she herself may be linked to Longlegs through forgotten childhood events and her strained relationship with her mother.
  • The investigation reveals that the killer has been circling her life for years, blurring the line between hunter and hunted and turning the case into a very personal reckoning.
  • Occult items like handmade dolls, mysterious metal objects, and ritual patterns hint that something beyond ordinary human evil may be driving the murders.

Tone and themes

  • The movie is known for its oppressive, slow‑burn atmosphere, more about dread and unease than jump scares.
  • It explores themes of parental abuse, trauma, religious and Satanic fanaticism, and how evil can infiltrate normal families under the surface.
  • Stylistically it feels like a mix of FBI true‑crime thriller and occult nightmare, with Nicolas Cage’s portrayal of Longlegs adding an intentionally exaggerated, uncanny presence.
