Season 4
Criminal Minds revolves around an elite team of FBI profilers who analyze America's most twisted criminal minds, anticipating their next moves before they strike again.
The Behavioural Analysis Unit's most prominent agent is David Rossi, a founding member of the BAU, who returns to help the team solve new cases, while pursuing some unfinished business of his own.
The team is led by Special Agent Aaron Hotchner, a family man who is able to gain people's trust and unlock their secrets.
Also on the team are Emily Prentiss, the daughter of high-powered diplomats, who recently joined the team and must prove her worth to Hotchner; Special Agent Derek Morgan, an expert on obsessional crimes; Special Agent Dr. Spencer Reid, a classically misunderstood genius whose social IQ is as low as his intellectual IQ is high; Jennifer "JJ" Jareau, a confident young agent who acts as the unit liaison for the team; and Penelope Garcia, a computer wizard who helps research the cases.
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.
Criminal Minds is produced by ABC Studios in association with CBS Television Studios.
