Brothers Under Fire is a 2026 American action thriller directed by Justin Chadwick and written by Delbert Hancock and Ian Mackenzie Jeffers. Originally announced under the title Sierra Madre, the film was later renamed ahead of its release. Led by Kiefer Sutherland, the cast also includes Ashton Sanders, Omar Chaparro, Laura Osma, and Solly McLeod. Set against the backdrop of northern Mexico, the story combines military action with a tense survival narrative as a group of soldiers find themselves outnumbered by a violent drug cartel.
Captain Jordan Wright and his squad are looking forward to a well-earned break as they travel to Mexico to attend a fellow soldier’s wedding. What begins as a joyful celebration quickly turns into a nightmare when a heavily armed cartel launches a brutal assault on the small village.
Separated from reinforcements and surrounded by enemies, Jordan must lead the remaining survivors through hostile territory while protecting both his men and the innocent civilians caught in the crossfire. With every escape route cut off, the squad is forced into a relentless fight for survival against an opponent that knows the terrain and shows no mercy.
As the conflict intensifies, Jordan discovers that courage alone may not be enough. Every decision carries life-or-death consequences, and the bonds between the soldiers are tested as they battle to make it home alive.
Brothers Under Fire was filmed in Colombia, with production beginning in late 2024. Director Justin Chadwick brings a grounded approach to the action, focusing on the camaraderie among the soldiers as much as the large-scale firefights. The film features cinematography by Toby Elwes, editing by Joshua Chadwick, and an original score composed by Alex Heffes.
Unlike many modern military thrillers that rely heavily on spectacle, Brothers Under Fire keeps its attention on the emotional strain of combat. The story explores loyalty, sacrifice, and leadership under impossible circumstances, while the remote village setting adds a constant sense of danger. The result is an action film that balances explosive set pieces with a more personal survival story.
Brothers Under Fire was released in select theaters and on digital platforms on April 17, 2026, distributed by Vertical. The film is available for digital purchase and rental, with streaming availability varying by region.
