When a gay man is murdered, seemingly the latest victim of a string of hate crimes, Brenda must confront prejudices inside and out of the LAPD. But when the perpetrator of the crimes turns out to be something quite different than expected, and has an alibi for the latest murder, Brenda must dig deeper to discover if this crime is part of the string, or a crime of passion disguised as a hate crime. Meanwhile, Flynn and Taylor step up their efforts to undermine Brenda once again, but with unexpected effects, as the team begins to rally around Brenda. Provenza's quirks begin to emerge, and we meet Terrence Hynes, a County Coroner's Forensics Support worker with an odd sense of humor. On the home front, Brenda finds herself with some new charges when her (male) Kitty has kittens.

When a few body parts of an "adult film" star are found in a dumpster, Brenda and the team must scramble for more pieces to solve this puzzle. Once they begin putting things together, the suspect list seems to get longer. Adding more questions to her life, Brenda also finds herself making a potentially life-altering discovery.

Leaving the scene of an accident to get to a multiple homicide scene, Brenda finds herself unable to drive the streets of L.A. which she worked so hard to learn. Once she gets to the crime scene, she and the PHD are faced with another challenge: the murdered bodies are nowhere to be found. In order to solve this case, they must first search for the victims before they can hunt for the killer.

Brenda and the PHD investigate the murder of a personal trainer who was involved with the wife of a possessive husband with a temper. Complicating the investigation: their only witness is the man's frightened valet, who also has OCD. Brenda must also solve the murder while sharing her squad with Homeland Security.

The body of a man who stole $3 million in diamonds is found in the trunk of a car; the condition of the body makes determining the cause of death impossible.

Brenda finds the case the perfect platform to play the role of teacher to Gabriel as he prepares for his detective exam. When Brenda's niece, Charlie, gets out of hand, she and Fritz must consider ending her summer vacation with them.
