Some stories survive in history books, while others remain trapped in the silence between what the world saw and what really happened behind closed doors. For 29 years, one of Spain’s darkest chapters has carried unanswered questions, unheard voices, and desperate attempts that never made it into the public story. Now, a new Netflix documentary is turning the clock back to the 48 hours that changed an entire nation forever.

And while the stories that remained untold for 29 years finally seem ready to open their cover pages, here is everything you need to know about Miguel Ángel Blanco: The 48 Hours That Changed Spain.

Miguel Ángel Blanco: The 48 Hours That Changed Spain reconstructs the July 1997 kidnapping and assassination of Miguel Ángel Blanco, a 29-year-old municipal councillor from Ermua. After abducting him, ETA gave the Spanish government 48 hours to transfer the group’s prisoners to prisons in the Basque Country, threatening to kill Blanco if its demand was rejected. As the deadline closed in, millions mobilized across Spain in a desperate show of solidarity, but when the ultimatum expired, Blanco was shot and later died from his injuries.

The 93-minute documentary goes beyond recounting the tragedy, examining the moment when fear began turning into collective resistance. Directors Jon Sistiaga and Juanjo López spent months reconstructing the timeline, examining more than 180 hours of archival footage alongside material from over 30 national and international audiovisual sources, newspapers, institutions, archives, and libraries. For Sistiaga, however, the story is more than history; he was also a 29-year-old reporter covering the crisis from the ground as those terrifying hours unfolded.

And while history already knows how those 48 hours ended, the documentary brings forward voices and attempted interventions that remained buried for nearly three decades.

Rather than relying on dramatic recreations, the documentary builds its story through nearly 30 firsthand testimonies from the people caught inside the crisis. Former Spanish Prime Minister José María Aznar, former Interior Minister Jaime Mayor Oreja, former Ermua mayor Carlos Totorika, and Blanco’s sister María del Mar Blanco are among the central voices revisiting the impossible decisions and unbearable uncertainty of those two days. King Felipe VI also reflects on experiencing the tragedy as the then-Prince of Asturias, who, like Blanco, was 29 years old at the time.

The documentary also brings together journalists, political figures, Blanco’s friends and bandmates, coworkers, police personnel, Ertzaintza officers involved in the search, and medical professionals who fought to save his life. Most significantly, María José Gurrutxaga and Patxi Zabaleta speak publicly for the first time about attempts to contact members of ETA and stop the assassination, addressing efforts that had been rumored for years but never openly confirmed by those involved. 

Miguel Ángel Blanco: The 48 Hours That Changed Spain will premiere globally on Netflix on July 10, 2026, arriving just days before the 29th anniversary of Blanco’s death. The timing carries a haunting symmetry: 29 years have passed since Spain lost the young councillor, who himself was only 29 when he was murdered. With a runtime of 1 hour and 33 minutes, the documentary condenses an enormous national tragedy into the two days when millions waited, marched, hoped, and ultimately refused to remain silent.

Directed by Jon Sistiaga and Juanjo López and produced by The Tintirin Team, the Netflix Original follows the production company’s previous collaboration with the streamer, UniverXO Dabiz. This time, however, the team turns toward one of the most painful and transformative chapters in Spain’s recent history, combining exhaustive archival research with voices that were actually inside the crisis.

And as Miguel Ángel Blanco: The 48 Hours That Changed Spain reopens the past nearly three decades later, be ready to witness the brutal truth that shook an entire nation and hear the voices history never got to hear.
