Following the massive success of DAHMER, Ryan Murphy and Ian Brennan’s true-crime anthology series returns with Monsters: The Lyle and Erik Menendez Story. It chronicles the case of the real-life brothers who were convicted in 1996 for the murders of their parents, José and Mary Louise “Kitty” Menendez. While the prosecution argued they were seeking to inherit their family fortune, the brothers claimed — and remain adamant to this day, as they serve life sentences without the possibility of parole — that their actions stemmed from a lifetime of physical, emotional, and sexual abuse at the hands of their parents.

Monsters: The Lyle and Erik Menendez Story dives into the historic case that took the world by storm and paved the way for audiences’ current fascination with true crime. It asks the question: “Who are the real monsters?” Stream it only on Netflix, Sept. 19.
