The next episode of "Criminal Minds" season 12 will see Emily Prentiss (Paget Brewster) and the team deal with one of the most horrifying faces of bullying.

Titled "The Anti-Terrorism Squad," episode 5 will see the Behavioral Analysis Unit (BAU) investigate the murders of two families that a couple of high school students escaped alive and well.

The synopsis for "Criminal Minds" season 12 episode 5 suggests that bullying had something to do with the tragedy. However, the promo warns that everything is not as it seems.

"Every clue is a deception and every victim is not who you think they are," the voiceover warned. In fact, as complicated as it already is, the BAU is just dealing a tip of a "really big iceberg."

Prentiss will once again lead this investigation, although fans can also expect her in the second season of "Criminal Minds: Beyond Borders."

Brewster's character will turn to the International Response Team of the Federal Bureau of Investigation (FBI) in closing open serial murder cases with ties to Taiwan.

"Criminal Minds: Beyond Borders" star Alana De La Garza tweeted a photo of her and Brewster behind the scenes during the filming of the episode in question.

It turns out that fans will be seeing a lot more of the character. Not only is she basically taking over for Hotch (Thomas Gibson) in "Criminal Minds" season 12, she will also pop by the spinoff.

Originally, Brewster was signed up for several episodes in this season of "Criminal Minds." However, with her show "Grandfathered" canceled and Gibson fired from the show, she ends up in a much bigger role.

For "Criminal Minds" season 12 episode 5, she will once again lead the team in bringing justice to the massacred family and knowing who is responsible.

The promo suggests that either the victims may not be as innocent as they are being shown or the killer planted clues to frame these poor kids with the root cause being a horrible case of bullying.

"Criminal Minds" season 12 episode 5, "The Anti-Terrorism Squad," will air on Wednesday, Nov. 2, at 9 p.m. ET on CBS.
