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

After admitting to the murders, Erik and Lyle begin to divulge details of the psychological and sexual abuse they suffered at the hands of their parents. However, a lack of tangible evidence to corroborate the claims leaves Leslie and Jill to wonder how they will convince a jury that the boys truly feared for their lives given the family's picture-perfect public persona. Meanwhile, Leslie makes a case for Dr. Oziel's tapes to be thrown out of court and Pam Ferrero faces increased pressure from the District Attorney's office in the shadow of Ira Reiner's re-election campaign and the polarizing decision to acquit the police in the Rodney King case.
