This release compiles every episode from season four of The Mentalist, the CBS series starring Simon Baker as Patrick Jane, a master of observation who helps the police solves crimes while simultaneously hunting for Red John, a killer who murdered Patrick's wife.

The first season of this crime drama finds Patrick Jane (Simon Baker) a former psychic, adjusting to his new job as a consultant for the California Bureau of Investigation. Jane's not big on following proper procedure, much to the chagrin of his boss, Agent Teresa Lisbon (Robin Tunney), but his keen powers of observation help them solve cases. Cases involving elusive serial killer Red John are of particular interest to Jane, because this killer murdered his wife and young daughter a few years prior. Some cases this season include the poisoning death of a country-club socialite and the murder of a Hollywood producer.
