However, his peace is shattered when he learns that a brutal cartel is terrorizing local villages, trafficking people, and causing widespread devastation.

Rambo initially refuses to get involved, but when he discovers that a group of mercenaries, led by a former military operative named Frank Keller (Jon Bernthal), is covertly working to take down the cartel, he is reluctantly drawn back into the fight. Keller, a younger and equally tough soldier, has a personal vendetta against the cartel, which murdered his family.

Despite their shared enemy, Keller and Rambo have different approaches and ideologies, leading to tension and mistrust between them.

As the story unfolds, Rambo and Keller are forced to work together, combining their skills and knowledge to dismantle the cartel’s operations. The film features intense action sequences, with Rambo utilizing his signature guerrilla warfare tactics and brutal efficiency to take down heavily armed foes. Keller, though skilled and ruthless, struggles with his own inner demons, mirroring Rambo’s struggles from his earlier years.
