There is no rest for the FBI’s Behavioral Analysis Unit (BAU). Last year saw Criminal Minds conclude its eighteenth season and the third season of the Evolution continuation on Paramount+, finally capturing serial killer Elias Voit (Zach Gilford) and taking down the Disciple (Jordana Spiro) along with him. After so many years of being pushed to their limits as they anticipated and confronted the worst of humanity, though, the profilers’ big break turns out to just be the beginning of their biggest test. Season 19 is right around the corner on May 28, and with it, the team is about to see just how contagious evil can be even after bringing one of their most elusive and twisted targets to justice and dismantling his network of killers.

Picking up where the previous finale left off, Criminal Minds: Evolution Season 19 kicks off a chilling string of new cases that have the BAU scrambling. Although Voit is safely behind bars awaiting arraignment and seeking to atone for his past, another formidable foe has emerged from his shadow — the Fan. This copycat killer was inadvertently born from Voit’s newfound infamy and haunts the team as he seeks not just to replicate but to surpass his idol’s work with frightening precision and careful planning. With their backs against the wall, the team will once again have to turn to their former foe for help cracking this difficult-to-read UnSub whose capacity for evil seemingly has no limits.

Ahead of the premiere, Paramount+ has shared the official trailer, teasing what’s next for the BAU and Sicarius as they reunite. After a chilling tease of the new UnSub, the footage cuts to the FBI as the team ponders whether there will one day be some clear behavioral link shared by all serial killers or if they’re all “sick snowflakes.” The BAU will certainly wish the former is true as they deal with Voit’s copycat. Given their similar methods, he’s practically a living resource on everything the Fan will do next, but there’s a level of desperation to prove themselves and a certain untraceability that will make them all the more dangerous. Worse, Voit hits the analysts with a harsh reality — even if they stop one copycat, there’s no telling how many others could keep the cycle of violence going. Either way, they’ll need him to reckon with the Sicarius Killer inside him to save lives in the here and now, though it’s unclear if he’ll be able to keep that side of him in check.
