Netflix Sets Spanish Crime Thriller ‘The Night Marta Disappeared’ Based on a True Story

Netflix is teaming up once again with Bambú Producciones—the powerhouse studio behind the massive international hit The Asunta Case—for another gripping true-crime dramatization. Production has officially started on En el nombre de Marta (The Night Marta Disappeared), a new Spanish limited series inspired by the tragic 2009 Marta del Castillo case.

If you were gripped by The Asunta Case or The Snow Girl, you’ll definitely want to keep this one on your radar. To bring this story to the screen, Bambú Producciones is co-producing alongside La Claqueta PC, and notably, the project has the official support of Marta del Castillo’s family.

Here’s everything we know so far about The Night Marta Disappeared.

What is the plot of The Night Marta Disappeared?

The six-episode limited series is a dramatized retelling of one of the most shocking and high-profile missing persons cases in modern Spanish history.

Here is the official logline provided by Netflix:

“On January 24, 2009, Marta del Castillo, a 17-year-old girl from Seville, disappears after leaving home to meet Miguel Carcaño. Within hours, what seemed like a typical teenage outing turns into a national tragedy. What follows is a nightmare for her family: contradictory versions, false confessions, a body that never appears, and a justice system that, despite handing down convictions, fails to offer solace.”

The series promises to be a meticulous and respectful reconstruction of everything that happened following her disappearance. It will chronicle the initial police investigations, the constantly changing stories from Miguel Carcaño and his accomplices, the ensuing media frenzy, and the relentless search for her body.

More importantly, it will focus on the family’s public battle against impunity, showing how the media fueled social tension and how the citizens of Spain turned Marta’s name into a powerful symbol for justice.

Who is behind the series?

The creative team behind the series features some heavy hitters in the Spanish television industry.

The Night Marta Disappeared is created and written by Ramón Campos, Gema R. Neira, Salvador S. Molina, Curro Serrano, and David Orea Arribas. Fans of Spanish Netflix Originals will recognize Campos and Neira as the core creative duo behind The Asunta Case, Cable Girls, High Seas, and the short-lived The Lady’s Companion.

Directing duties for the six episodes are being shared by Carlos Sedes, Laura Alvea, and José Ortuño.

Who is in the cast of The Night Marta Disappeared?

Netflix has announced a stellar ensemble cast for the miniseries. While exact character details are currently being kept under wraps, the confirmed cast list includes:

• Blanca Portillo (Maixabel, Volver)
• Vicente Romero (Express, Cell 211)
• Verónica Sánchez (Sky Rojo, The Pier)
• María León (The Sleeping Voice, The Fariña)
• Paco Tous (Best known to Netflix fans as Moscow in Money Heist)
• Hugo Welzel (The Snow Society)

What is the production status, and when will it be released on Netflix?

Filming for the series officially kicked off on April 21, 2026, with cameras currently rolling on location in Seville, Spain—the very city where the real-life events took place.

Since production is just getting underway, Netflix hasn’t set an official release date yet. Given the typical production cycle for a six-episode European drama, we expect the series to wrap up filming by late summer, placing The Night Marta Disappeared on track for an early-to-mid 2027 release.
