Monster: the story of Lizzie Borden arrives on Netflix on September 17

The fourth season of Monster now has a date. Titled Monster: The Lizzie Borden Story, it will be available on Netflix on September 17, 2026. The anthology created by Ryan Murphy and Ian Brennan will focus this time on the criminal case of Lizzie Borden, in Massachusetts.

Netflix has confirmed the release date, unveiled the first images, and presented part of the cast. Ella Beatty will play Lizzie Borden, alongside Charlie Hunnam, Rebecca Hall, Vicky Krieps, Billie Lourd, Jessica Barden, and Sarah Paulson.

The platform presents this program as the fourth installment of its anthology. The previous three seasons focused on Jeffrey Dahmer, Erik and Lyle Menendez, and then Ed Gein. This new story places a woman accused of murder at the center of the narrative for the first time.

Netflix has already released a teaser and also points to a full trailer. The Tudum article published on August 20 accompanies these videos with a synopsis and a gallery of photos, but keeps a large part of the plot off-screen.

A Criminal Case from 1892

The narrative is based on the Lizzie Borden case. In 1892, Lizzie Borden was accused of murdering her father, Andrew Borden, and her stepmother, Abby Borden. This accusation provides the historical starting point for the season.

The series does not treat this subject as a simple judicial recreation. Netflix presents it as a fiction centered around Lizzie, her family, and Bridget Sullivan, the Borden’s maid. The official synopsis mentions a climate of cruelty, a desire for revenge, and fantasies that must weigh on the relationships between the characters.

The official information currently allows us to identify the subject, the casting, and the release date. It does not specify the link between the two cases referred to by the cast, nor the number of episodes.

Ella Beatty in the Lead Role

Ella Beatty will play the role of Lizzie Borden. In Monster, she will portray a historical figure whose name is still associated with a criminal accusation over a century old.

The cast announced by Netflix includes:

• Vicky Krieps as Bridget “Maggie” Sullivan, the Borden maid;
• Charlie Hunnam as Andrew Borden, Lizzie’s father;
• Rebecca Hall as Abby Borden, her stepmother;
• Billie Lourd as Emma, Lizzie’s older sister;
• Jessica Barden as Nance O’Neil, an actress close to Lizzie.

Thus, the cast places the family affair in the spotlight. Netflix identifies Andrew as Lizzie’s father, Abby as her stepmother, and Bridget Sullivan as the maid who lives with the Bordens. The platform does not provide further details on the dramatic progression.

Sarah Paulson will play Aileen Wuornos

Sarah Paulson also joins the season in the role of Aileen Wuornos. Netflix confirms this casting information, without explaining how this character fits into the story dedicated to Lizzie Borden.

Netflix Launches Monster on September 17

Monster: The Lizzie Borden Story will arrive on Netflix on September 17, 2026. Netflix uses this title on its Tudum page dedicated to the season.

The first information outlines a season focused on Lizzie, the Borden house, and the characters announced around her. The rest will depend on the release: Netflix has given the date, the cast, and a synopsis, without revealing the entirety of the narrative.
