The BAU travels to Chicago to investigate an unsub who leaves red roses on each victim. Also, Rossi gets an unexpected visit from his ex-wife, Krystall Richards.

The BAU team heads to Portland, Ore., to investigate a chilling abduction that may be linked to a local couple killed in their home a week earlier.

Prentiss and the team fly to Iowa to investigate the disappearance of three 10-year-old children who appear to have been abducted from their homes in the middle of the night, with surveillance video from a neighborhood park as their only lead to finding the children’s whereabouts.

Wedding bells are ringing as Rossi prepares to marry Krystall. But first, the BAU team travels to Los Angeles to investigate a series of fatal shootings in broad daylight following car accidents.

It has been a year since Rossi nearly died at the hands of Everett Lynch, a.k.a. “The Chameleon,” and he has developed some new theories, with inspiration from his former partner, Jason Gideon. The BAU team sets out on an epic hunt to capture Lynch.
