Special Agents Jason Gideon (Mandy Patinkin) and Aaron Hotchner (Thomas Gibson) head up the FBI's most elite profiling team - experts in analysing criminal minds. Each team member has their specialty. There's Elle Greenaway (Lola Glaudini), who has a background in sexual offences; Derek Morgan (Shemar Moore), who focuses on obsessional crimes; Special Agent Dr. Spencer Reid (Matthew Gray Gubler), the smart but socially challenged genius; and Jennifer "JJ" Jareau (A.J. Cook), the rookie. With each mind-blowing case, they put their lives on the line as they match wits with the most ruthless criminals on earth.
