Netflix’s ‘Under Siege’ Release Date, Trailer, Cast, and What the Series Is About

Netflix’s ‘Under Siege’ is a Colombian limited series that dramatizes one of the most painful chapters in the country’s recent history. Netflix has confirmed that it arrives on November 6, 2026, and an official trailer has already been released. The streamer is positioning it as a serious, research driven drama rather than a conventional thriller.

The series is known in Spanish as ‘Palacio’ and runs eight episodes, reconstructing the guerrilla takeover of Colombia’s Palace of Justice and the military retaking that followed. Below is everything currently known about ‘Under Siege’, from its premiere date and production details to its cast and story.

‘Under Siege’ Release Date on Netflix

Netflix has set the premiere of ‘Under Siege’ for November 6, 2026. The project is a Colombian Netflix Original, and the platform lists it as a limited series with a single season of eight episodes.

The timing is deliberate. Netflix chose the same calendar date on which a guerrilla commando seized the Palace of Justice in Bogotá’s Plaza de Bolívar in 1985. The premiere also coincides with the forty first anniversary of the events.

The series was produced by Dynamo, the Colombian company that also made ‘Cien años de soledad’ for Netflix. Local outlet IFM Noticias reported that ‘Under Siege’ headlines the platform’s November premieres.

The ‘Under Siege’ Trailer and Production

Netflix released an official trailer alongside the date announcement. According to the press release, the first look offers a perspective shaped by more than seven years of research drawn from documents, testimonies and interviews.

The series was filmed primarily in Bogotá on a set covering more than 4,000 square meters that took over three months to build. The production also included a 30 meter structure recreating the original façade of the Palace of Justice.

Natalia Santa serves as showrunner and co-wrote the series with Enrique Videla, Enrique Lozano, Jenny Ceballos and Estefanía Piñeres. Jayro Bustamante directed the first three episodes, Edgar Nito directed the next three, and Samir Oliveros directed the final two. Speaking with CAMBIO, Santa said that for many years several writers, directors and producers had wanted to tell the story of the Palace of Justice.

Bustamante is known for films such as ‘Ixcanul’ and ‘La Llorona’. After the trailer appeared, he said it was an honor to be part of the series and to approach a story that deeply marked Colombia and Latin America.

‘Under Siege’ Cast and Characters

Natalia Reyes plays Pilar Navarrete, and she previously starred in Netflix’s Mexican drama film ‘A Father’s Miracle’. She leads an ensemble that, according to Infobae, portrays a number of real figures connected to the events.

Carlos Manuel Vesga plays Colonel (Ret.) Alfonso Plazas Vega, while Robinson Díaz plays Belisario Betancur. Vesga has appeared in several Netflix projects, including ‘The Hijacking of Flight 601’.

The supporting cast includes Luna Baxter as Olga Behar, Mariana Gómez as La Mona, Santiago Alarcón as Alfonso Reyes Echandía and Nicole Santamaría as Angela María Buitrago. Andrés Castañeda appears as Eduardo Umaña and Camilo Amores plays Jimmy Beltrán, among a larger group of performers.

What ‘Under Siege’ Is About

On November 6, 1985, a guerrilla commando forcibly entered the Palace of Justice and took more than 300 people hostage, including Supreme Court justices. The following day, the Colombian Army retook the building.

The series recounts both the siege and the retaking, which resulted in the deaths and disappearances of at least 94 people, including justices, guerrilla members, civilians and members of the military. Netflix describes it as a fictional series inspired by real and publicly known events.

The story does not end when the building is retaken, since it also follows the victims’ families in their pursuit of justice for more than 20 years. The Hollywood Reporter earlier described the project as a look at the standoff and its lasting national impact. With the series landing on the anniversary of the siege itself, do you think its focus on the families’ two decades of searching for answers will change how audiences understand the story of the Palace of Justice?
