In Season 9 of the mind-blowing series Criminal Minds, FBI's Behavioral Analysis Unit (BAU) knows no boundaries when it comes to tracking down ruthless and unpredictable killers. Unit chief Aaron Hotchner (Thomas Gibson) and Special Agents David Rossi (Joe Mantegna), Alex Blake (Jeanne Tripplehorn), Dr. Spencer Reid (Matthew Gray Gubler), Derek Morgan (Shemar Moore) and Jennifer "JJ" Jareau (A.J. Cook) use the scientific art of profiling and psychological tactics to solve the FBI's most extreme and violent cases. With the help of skilled hacker and technical analyst, Penelope Garcia (Kirsten Vangsness), the BAU takes down serial killers, uncovers dark secrets, and saves lives - including one of their own.
CRIMINAL MINDS revolves around an elite team of FBI profilers who analyze the country's most twisted criminal minds, anticipating their next moves before they strike again. The Behavioral Analysis Unit's most prominent agent is David Rossi (Joe Mantegna), a founding member of the BAU, who returns to help the team solve new cases, while pursuing some unfinished business of his own. Each member brings his or her own area of expertise to the table as they pinpoint predators' motivations and identify their emotional triggers in the attempt to stop them.
