CRIMINAL MINDS “Mayhem” (Season 4 Episode 1) September 22, 2008 Criminal Minds Check out some pictures from CRIMINAL MINDS‘ Season 4 premiere episode, “Mayhem,” airing this Wednesday, September 24, at 9pm on CBS. Criminal Minds returns for an all new season this week. I will be honest here and admit that I cannot really remember last season’s finale, but this is the beauty of procedurals, you don’t need to remember. It does look like the team gets right back into it going after terrorists, that’s a change! You can watch a promo and check out more photos from Criminal Minds “Mayhem” below.

Episode Synopsis: “Mayhem” – When an SUV carrying members of the BAU explodes, the rest of the team fights to save their colleagues and catch the terrorists responsible for the bombing.
