MindhunterDavid Fincher returns to "Zodiac" territory for his first series, "Mindhunter," about the formation of the FBI's Elite Serial Crime Unit, and it looks appropriately dark and disturbing.

Set in 1979, the series stars Jonathan Groff (doing a huge 180 from "Glee" and "Frozen") as Holden Ford, an unconventional agent in the FBI's Behavioral Science Unit. Ford meets resistance when he wants to study serial killers like Charles Manson in order to stop them. He's partnered with Holt McCallany of "Criminal Minds" and the short-lived boxing series, "Lights Out." McCallany also played the imposing Mechanic in Fincher's "Fight Club."

It's based on the 1996 book by John Douglas and Mark Olshaker about the FBI's Investigative Support Unit. Per the book jacket, Douglas was the model for Scott Glenn's character Jack Crawford in "The Silence of the Lambs." His cases included the Atlanta child murders and Seattle's Green River killer, although we don't if those will be featured in the series.

It will be dealing with the notorious BTK Killer, since there's a listing for "Dennis Rader" on IMDb.

Fincher is producing the series and directed three of the 10 episodes in the first season. Anna Torv of "Fringe" costars.

"Mindhunter" debuts on Netflix on October 13.
