Two-time Oscar nominee Mary McDonnell stars in this spin-off of "The Closer", taking the detectives in the Los Angeles Police Department's Major Crimes division into bold new territory. As the new boss, McDonnell's Captain Sharon Raydor is determined to lead the department with a more team-oriented approach, sharing the credit with the people with whom she works. The show focuses on how the American justice system approaches the art of the deal as law enforcement officers and prosecutors work together to score a conviction.

Season four focuses on themes of courage, both in the personal and professional lives of the squad. Plus, Rusty, who is now officially adopted by Sharon, finds a passion that drives him — something Provenza is not too pleased about.

In season five the squad must solve some of the most challenging homicides in America’s second largest city. From searching for a missing teenage girl who vanished while helping the homeless, hunting down the killer of a potentially dirty cop or following up on a beheading in an isolated corner of Los Angeles, the investigators attempt to return balance to the scales of justice. Also this season, Sharon strives to push Rusty through college while figuring out where she wants to go in her ongoing romance with Andy Flynn; Julio Sanchez decides to try to adopt a child himself; Provenza develops sensitivities related to his new marriage to Patrice; Buzz Watson picks up the 30-year-old murder investigation of his father and uncle; Mike Tao wins an award for his work as a Hollywood consultant; and Amy Sykes confronts the idea of motherhood versus focusing on her career.

The elite team of Major Crimes is back for its sixth and final season with some of the most challenging cases yet, struggling to solve mysteries mired in complex political conflicts that move beyond traditional murder cases. As Sharon Raydor grows accustomed to her new boss, Assistant Chief Leo Mason, the detectives find themselves questioning their faith in the rapidly changing priorities of the justice system while also managing the difficult changes in their personal relationships. Finally, they must accept the necessity of risk, as they prepare to face the inexplicable but undeniable return of Phillip Stroh.
