Years after the bloody events of Rambo: Last Blood, John Rambo has vanished from the radar, presumed dead by most. But deep in the Alaskan wilderness, he lives off the grid—scarred, broken, and haunted. His days of war are over… until a ghost from his past reawakens the fire inside him.

News reaches Rambo that a covert CIA program once tasked with monitoring Vietnam POWs has resurfaced—this time, experimenting on forgotten soldiers for black ops missions. One of these soldiers, codenamed “Shadow,” is rumored to be Rambo’s own biological son, taken as a baby during a classified mission decades ago. Now a deadly operative unknowingly serving corrupt interests, Shadow is being deployed to silence whistleblowers across Central America.

Rambo’s quiet exile ends as he embarks on a desperate mission: not to kill, but to save the last piece of family he never knew he had. Traveling through violent jungles and war-torn villages, Rambo unleashes his brutal expertise—knives, traps, and guerilla tactics—on a younger generation of mercenaries and drones. Each confrontation brings him closer to the truth, and to a final reckoning with the man his son has become.
In a fiery climax, Rambo faces Shadow atop a drug warlord’s fortress. But instead of killing him, Rambo forces his son to remember who he really is. When the corrupt agency attempts to airstrike the compound to erase all evidence, father and son fight side by side in one final stand.
The film ends with Rambo gravely wounded, sitting beside his son on a cliffside. “War made me who I was,” he says, “but love… love made me fight for something more.”
