Bosco and his agents are gunned down within the walls of CBI headquarters. With two men dead and Bosco in a critical condition, Lisbon and her team race to find the perpetrator. As the investigation progresses, it becomes clear that notorious serial killer Red John is responsible - and he has an assistant inside the department.

The team investigate bank robberies where victims were forced to undress during the ordeal. The robber's behaviour begins to escalate from the search for profit to the abuse of captives.

Everything goes out of control when Reese joins the army; Hal is accused of insider trading; Lois falls into a catatonic state.

Convinced he will be sent to jail, Hal imparts fatherly advice and confesses to Malcolm about his poor work ethic.
