The Mentalist follows Golden Globe Award nominee Simon Baker as Patrick Jane, an independent consultant with the California Bureau of Investigation (CBI) who has a remarkable track record for solving serious crimes by using his razor sharp skills of observation. Within the Bureau, Jane is notorious for his blatant lack of protocol and his semi celebrity past as a psychic medium, whose paranormal abilities he now admits he feigned. Jane’s role in cracking a series of tough high-profile cases is greatly valued by his fellow agents. No-nonsense Senior Agent Teresa Lisbon leads the CBI team, which includes agents Kimball Cho, Wayne Rigsby and rookie member Grace Van Pelt, who all think Jane’s a loose cannon but admire his charm and knack for clearing cases. The real reason for Patrick Jane’s involvement with law enforcement is to track down the serial killer known as Red John, who was responsible for the brutal murders of his wife Angela Jane and his daughter Charlotte Jane.
The Mentalist runs for seven seasons with each episode from series 1-6 referencing the colour the red. This ends mid series 6 with the episode “Red John”, all the episodes which follow after reference other colours relevant to the story line.
