Netflix has confirmed that Under Siege, its new original Colombian series inspired by the 1985 Palace of Justice siege, will arrive on the platform on November 6, 2026. The production, consisting of eight episodes, recreates one of the most tragic episodes in Colombia's recent history through a cast led by Natalia Reyes, Carlos Manuel Vesga, and Robinson Diaz.
The series is directed by showrunner Natalia Santa, who also co-wrote the script alongside Enrique Videla, Enrique Lozano, Jenny Ceballos, and Estefanía Piñeres. Directing duties are shared by three filmmakers: Jayro Bustamante, Edgar Nito, and Samir Oliveros. The project is produced by Dynamo, with Mariana Berenguer and Mirlanda Torres as producers, and Andrés Calderón and Torres as executive producers.
Netflix has already released an official trailer for the series, which joins other Colombian titles in the catalog focused on historical events in the country.
When does Under Siege premiere on Netflix?
Netflix has officially confirmed that Under Siege will arrive on the platform on November 6, 2026. The date coincides, symbolically, with the anniversary of the events that inspire the plot, as the assault on the Palace of Justice began precisely on November 6, 1985.
What is Under Siege about?
According to the official synopsis released by Netflix, the series is inspired by real and publicly known events. The plot begins on November 6, 1985, when an M-19 guerrilla commando forcibly broke into the Palace of Justice and took more than 300 people hostage, including Supreme Court magistrates.
The following day, November 7, the Colombian Army retook the building. The operation to seize and retake the Palace left at least 94 people dead or missing, including magistrates, guerrillas, civilians, and military personnel.
Under Siege is not limited to reconstructing those 48 hours, but also follows the victims' families in their search for justice for more than two decades after the events.
