Paramount+ has dropped the official trailer for Season 19 of Criminal Minds: Evolution, which finds Elias Voit back to help find a killer who idolizes him.

The trailer also gives us a quick glimpe of Heated Rivalry‘s Connor Storrie, who is set as a guest star in the upcoming season. In addition to Storrie, guest stars also include Justin Kirk, Yvette Nicole Brown, Jeri Ryan, Clark Gregg, Paul F. Tompkins, Cress Williams, Kofi Siriboe, Dash Mihok, and Nicholas Gonzalez. 

Season 18 — with more talk about serial killers, sadistic psychopaths and Elias Voit, the notorious Sicarius Killer played by the enthusiastic Zach Gilford — picked up six months after prisoners attacked Voit, leading his restless followers on the dark web to begin wreaking havoc all over the country. In order to stop this group from killing more women, er, innocents, the BAU was forced to play a “real-life game of Clue” while saying things like “yes indeedy” as they worked alongside the increasingly unpredictable Voit (who seems to stick to his own agenda).

Per the logline: In Season 19, the elite profilers are pushed to their limits. As the BAU investigates a string of chilling new cases, Elias Voit embarks on a path to atone for his past. His newfound infamy inadvertently awakens their most formidable nemesis yet, The Fan. Precise, calculating, and relentlessly dangerous, this UnSub pushes the BAU to the brink and back under the shadow of Elias Voit. But how far will The Fan go to prove his superiority over his idol?

Starring Joe Mantegna, A.J. Cook, Kirsten Vangsness, Aisha Tyler, Zach Gilford, and RJ Hatanaka with Adam Rodriguez and Paget Brewster, Criminal Minds: Evolution follows the FBI’s Behavioral Analysis Unit, a team of profilers tasked with analyzing and capturing the country’s most dangerous criminals, before they strike again. 

Criminal Minds: Evolution is produced by 20th Television and CBS Studios. Erica Messer (Criminal Minds, Criminal Minds: Beyond Borders) serves as showrunner and executive producer. Breen Frazier, Chris Barbour, Glenn Kershaw, and Mark Gordon also executive produce.
