Get ready for a deep dive into one of Mexico’s most chilling true crime stories. The notorious case of the González Valenzuela sisters, known as “Las Poquianchis,” shook the nation in the 1960s. These women faced charges of human trafficking, exploitation, and murdering dozens of young women across Guanajuato and Jalisco. Their horrifying saga continues to grip imaginations, inspiring books, films, and now a major Netflix series.
More than five decades later, the story resurfaces with “Las Muertas” (The Dead Women), a six-episode limited series hitting Netflix globally on September 10, 2025. This new show, directed by acclaimed Mexican filmmaker Luis Estrada, takes its inspiration from Jorge Ibargüengoitia’s novel of the same name. But before “Las Muertas,” another iconic film tackled this dark chapter. In 1976, director Felipe Cazals brought the case to the big screen with his classic film, also titled “Las Poquianchis.” It was a powerful social commentary, a landmark of new Mexican cinema. Now, almost 50 years later, Estrada offers a very different take on the same grim material.
What Does “Poquianchi” Mean?
It’s worth a moment to understand the nickname tied to this infamous case. The word “poquianchi” isn’t found in the Spanish Royal Academy dictionary (RAE). However, in everyday Mexican speech, it describes someone “petty, stingy, miserable, or mean.” The sensationalist newspapers of the 1960s, particularly the weekly “¡Alarma!”, seized on this term. They used it to label the González Valenzuela sisters, loaded with a derogatory tone that forever stuck to their criminal history.
Realism vs. Satire
The biggest difference between the two productions lies in their approach. Cazals’ 1976 film, “Las Poquianchis,” is brutally raw. With a style almost like a documentary, the director showed the harsh realities of rural poverty, corrupt officials, and the exploitation of women in brothels without holding back. Viewers got no break; every scene aimed to outrage and force a confrontation with the Mexico of that era.
In contrast, “Las Muertas” starts from Ibargüengoitia’s novel, which twists the horror into satire. Luis Estrada captures this ironic viewpoint and brings it to the screen with dark humor, sharp dialogue, and a tone that swings between mockery and tragedy. Instead of Cazals’ stark visuals, “Las Muertas” boasts a big production that highlights the grotesque and absurd parts of the events.
The Characters
In Cazals’ “Las Poquianchis,” the criminal sisters appear as women hardened by greed, with no room for emotional depth. The goal was to expose a rotten system, not to make them seem human.
“Las Muertas,” on the other hand, offers a fuller picture. Arcángela (played by Arcelia Ramírez) and Serafina Baladro (played by Paulina Gaitán) are complex figures. They are devout, obsessive, yet capable of both kindness and cruelty. Estrada plays with the irony that these women pray to the Virgin Mary while also kidnapping young girls for exploitation. The cast also includes Joaquín Cosío as the crooked Captain Bedoya, Alfonso Herrera as Simón the baker, and Mauricio Isaac as the memorable Calavera.
The Message
Both works aim to highlight corruption and injustice, but they use opposite tactics. “Las Poquianchis” tries to move and shock its audience. “Las Muertas” seeks to provoke a bitter laugh and thought through political satire.
Simply put, Cazals shouted the truth in a country that didn’t want to hear it. Estrada sticks closer to Ibargüengoitia’s work, which, in turn, dresses up the story as a black comedy so that modern viewers can see themselves in that distorted mirror.
Two Visions, One Enduring Horror
The “Poquianchis” case was so brutal that it continues to inspire stories almost half a century later. Cazals’ film and Estrada’s series both stem from the same origin, but each speaks to its own time: a raw accusation in the 70s and a grand satire in 2025.
Even though the style changes, the message remains the same: a powerful reminder that violence, corruption, and exploitation in Mexico are not just things of the past.
