After Jose and Kitty Menendez (Carlos Gomez and Lolita Davidovich) are found murdered in their upscale Beverly Hills home, their eldest son, Lyle (Miles Gaston Villanueva), maintains a stoic appearance while his younger brother, Erik (Gus Helper), struggles to deal with overwhelming grief. As detectives Les Zoeller (Sam Jaeger) and Tom Linehan (Cliff Chamberlain) search for the killers, evidence begins to suggest that Lyle and Erik may be the prime suspects. Meanwhile, a tenacious and energetic defense attorney, Leslie Abramson (Edie Falco), takes an interest in the case.

When people surrounding the successful television actress start dying, Gideon and Dr. Reid call in the rest of the Behavioral Analysis Unit to assist with the case. As the team tracks down a stalker turned serial killer, Dr. Reid finds himself in danger as he grows closer to the actress in jeopardy.

Seemingly innocuous comments Lyle (Miles Gaston Villanueva) previously made about his parents come back to haunt him when detectives Zoeller (Sam Jaeger) and Linehan (Cliff Chamberlain) begin to interview the brothers' friends and acquaintances. Erik (Gus Halper), overcome by guilt, makes a shocking confession to his psychologist, Dr. Jerome Oziel (Josh Charles). Having overheard a therapy session with Lyle and Erik, Oziel's mentally unhinged mistress Judalon Smyth (Heather Graham) goes to the police with a pivotal tip after Oziel tries to cut ties with her to protect his family. As attorney Leslie Abramson (Edie Falco) learns more about the Menendez family dynamics, she makes a move to represent the brothers.

The BAU travels to Los Angeles looking for an UnSub who is kidnapping nannies and the children they care for on the same day each year.

With Lyle (Miles Gaston Villanueva) and Erik (Gus Halper) in custody for suspicion of murder, defense attorney Leslie Abramson (Edie Falco) works tirelessly alongside Jill Lansing (Julianne Nicholson) to understand the motive that could drive two young men to commit such a heinous crime. Meanwhile, the prosecution puts Judalon Smyth (Heather Graham) on the stand to make a case for releasing Dr. Oziel's (Josh Charles) audio notes and tapes from his sessions with Lyle and Erik, despite standard doctor patient privilege. The ensuing media circus fueled by leaks from the District Attorney's office creates further complications for the defense and places the extended Menendez family at odds with one another.
