The detectives in the Los Angeles Police Department's Major Crimes division are still reeling from the departure of Brenda Leigh Johnson and the realization that Captain Raydor is now in charge.
Unlike their previous chief, Raydor is determined to lead the department with a more team-oriented approach, sharing the credit with the people with whom she works.
Raydor's hardest job, however, will be gaining the full trust and confidence of her detectives, who aren't quick to forget her long history of internal investigations targeting them and their previous boss.
Especially troublesome is Provenza, who has a difficult time taking orders from someone he doesn't think knows as much as he does.
Mary McDonnell stars in the series, continuing her Emmy-nominated role from The Closer. Joining her are fellow Closer veterans G.W. Bailey, Tony Denison, Michael Paul Chan, Raymond Cruz and Phillip P. Keene.
In addition, Robert Gossett, Jon Tenney and Jonathan Del Arco guest-star in several episodes, with Del Arco being promoted to series regular in Season 2.
The series also stars Graham Patrick Martin as Rusty, a homeless juvenile whose character was introduced in the final episode of The Closer, and Kearran Giovanni as Detective Amy Sykes, an ambitious undercover police detective and military veteran who served in Afghanistan. Nadine Velazquez joined the ensemble as Deputy District Attorney Emma Rios in Season 2.
Major Crimes is produced by The Shephard/Robin Company, in association with Warner Bros. Television. The Closer's James Duff, Greer Shephard, Michael M. Robin, and Rick Wallace serve as executive producers on the series.
