Thaddeus "Thunderbolt" Ross stands at a podium as the film opens, now President of the United States, and pledges that his administration will face threats the country has never seen before. Television anchors and pundits narrate footage of Ross's past: his explosive temper, the public outcry after the Hulk and Abomination destroyed parts of Harlem, and his estrangement from his daughter Betty Ross. Reporters trace a line from those events to Ross's new, hardline posture in office even as he prepares to preside over delicate international negotiations.

Five months later, Sam Wilson, operating as Captain America, and Joaquin Torres, who serves as Falcon, execute an operation in Oaxaca, Mexico under Ross's orders to dismantle a cell of the mercenary outfit known as the Serpent Society. The pair move through a church where Sidewinder, the Serpents' leader, holds civilians hostage. Sam intercepts the hostage taker, deploying his wings and shield in precise aerial and hand-to-hand maneuvers to neutralize the mercenaries. While Sam grapples with a larger enforcer, Sidewinder slips away; Joaquin, in his Falcon armor, pursues other Serpent operatives and successfully intercepts a crate the group intended to sell to a mysterious buyer. When the mission concludes, Sam pockets the recovered package and radios a status report to President Ross.

Back in Baltimore, Sam and Joaquin train with Isaiah Bradley, an elder veteran whose complicated history with the government looms over their relationship. Ross extends an invitation to Sam, Joaquin, and Isaiah to attend a gathering at the White House; Isaiah warns Sam against trusting the government that betrayed them both, but Sam insists on attending because he wants to change how things are done from the inside.

At the White House summit, Ross stands before assembled world leaders and guests to announce the discovery of a new metal--adamantium--on an exposed fragment of a Celestial they call Celestial Island. Ross proposes an international treaty to manage mining and distribution of the metal, arguing a coordinated approach will prevent an arms race. He then calls Sam aside to discuss a proposal: Ross wants Sam to lead a reconstituted Avengers initiative. Sam voices hesitation, recalling past abuses of power tied to international accords, but Ross presses the point that they can do things differently with Sam at the helm.

The meeting turns violent when an old pop song, "Mr. Blue," begins to play in the background. Several men seated among the dignitaries, including Isaiah and four other individuals, rise and open fire on the podium. Ruth Bat-Seraph, Ross's head of security and a former Black Widow operative, springs into action and neutralizes several shooters. Sam pursues Isaiah through the White House grounds, sprinting, gliding, and confronting him in a park. Isaiah suddenly snaps back to awareness amid the chaos; Sam persuades him to put his hands up and surrender rather than risk being killed or shot by security forces. Ross orders Sam to stay away from the investigation, telling him he is too emotionally connected to Isaiah to be objective.

Sam refuses to obey that order. He and Joaquin analyze surveillance footage and discover a recurring artifact: every shooter's phone flashes a tiny blinking signal just before they act. A few days later, Sam is ambushed on the street by Sidewinder, who attempts to blow up Sam's car and then fights him with a pistol and a serpentine energy weapon. Sam disarms and subdues Sidewinder in close combat, leaving him in custody, and brings Sidewinder's phone to Joaquin for forensic tracing. The call history points to a hidden, off-grid black site known as Camp Echo One--a remote facility in West Virginia where classified experiments are run.

While Sam and Joaquin move on that lead, Ruth monitors a correctional facility where the arrested shooters are held. A guard inexplicably pulls a handgun, murders several of the imprisoned shooters while "Mr. Blue" plays over a radio, and then turns the weapon on himself. Ruth arrives at the scene and finds the bodies; the sequence underscores that the "Mr. Blue" signal can still trigger violence even away from the White House.

Sam and Joaquin infiltrate Camp Echo One, slipping past perimeter defenses with the help of Sam's drone Redwing. Inside, they uncover genetic files and lab notes cataloging people who were exposed to gamma-related research, including Isaiah. In a central lab they confront the architect behind the contagion of influence: Dr. Samuel Sterns, known to some as the Leader. Sterns displays a severely mutated cranial growth and an unnerving intelligence; he reveals he gained a dramatic increase in cognitive function after exposure to Bruce Banner's blood during the Harlem incident. Sterns explains, through taunting and clinical detail, how he uses technology linked to audio micro-signals to override neural pathways--his "Mr. Blue" pattern can compel people to act without conscious volition. Sterns leaves Sam and Joaquin restrained in the lab long enough for mercenaries paid by him to swarm the corridors; the two of them fight through the hired soldiers until Ruth appears, physically dismantles another squad, and frees them. As the trio exits the facility shouting for time, soldiers and law enforcement arrive; then, with "Mr. Blue" broadcasting again, several officers become puppets and attempt to kill Sam and Joaquin. Sam throws his shield to knock the shooters off balance and he, Joaquin, and Ruth seize a government van to escape.

Meanwhile, Ross scrambles to salvage the treaty. The Japanese Prime Minister Ozaki blames Ross for the theft of Japanese adamantium samples and for the breach at the White House, and foreign leaders begin to pull diplomatic support. Ross becomes increasingly agitated; his staffers and Secret Service detail, including Leila Taylor, try to keep him composed. Sam brings evidence from Camp Echo One to his military contact Dennis Dunphy and asks Dunphy to run tests on vials and pills found in Sterns's laboratory. Dunphy identifies gamma signatures in the compound and confirms that the tablets are delivering controlled pulses of gamma-infused compounds.

Sam returns to question Sidewinder while the villain is detained. Sidewinder reveals that Sterns hired the Serpent Society to steal refined pieces of adamantium and sabotage the treaty to drive geopolitical tension--Sterns seeks to ruin Ross's legacy and to destabilize global power balances. Sam cross-references Sidewinder's information with Camp Echo One's data and concludes Sterns's reach extends into the military.

Sterns escalates by murdering an admiral and thereby seizing access to a military-frequency transmitter that amplifies "Mr. Blue." He then manipulates two U.S. F-18 pilots, bringing them under his influence and sending them to intercept a Japanese fleet that has arrived at Celestial Island to assert Japan's claim on recovered adamantium. At the same time, Ross reveals to Sam in a heated private exchange that he is dying of heart failure and that, seeking to extend his life, he kept Sterns imprisoned at Camp Echo One to produce experimental pills infused with gamma compounds. Ross admits he refused to release Sterns because Sterns's pills are the only thing that has kept Ross alive; Sterns's resentment toward being held drove the campaign of revenge.

On the open sea near Celestial Island, two fighter jets roar toward a Japanese task force. Sam and Joaquin launch in response. Sam intercepts one F-18 in the air and uses precise maneuvers to force the pilot to eject while Joaquin confronts the second aircraft. As Joaquin's craft collides near the water, an explosion sends Joaquin tumbling into the surf; Sam rescues Joaquin from the ocean but sees he has sustained critical injuries from shrapnel and impact. Paramedics later wheel Joaquin into intensive care, where doctors stabilize him. The Japanese fleet stands down after Sam and Joaquin's intervention and after Ozaki receives confirmation that the U.S. is not responsible for the attack.

Sterns murders Dennis Dunphy after Dunphy discovers the truth about Ross's pills. Sterns confronts Dunphy in a confined space and uses a device that emits a focused electromagnetic pulse which stops Dunphy's heart, killing him instantly. Sterns uses Dunphy's death to ensure no one else can expose the gamma-laced tablets that have been saturating Ross's bloodstream. Shortly afterward, Sterns turns himself in to authorities, arranging for Sam to take him into custody. Before he is escorted away, Sterns warns Sam that the final part of his scheme will be visible to the entire nation: he intends to show the world that Ross is literally a monster.

At a high-profile press conference intended to reassure the public, Sterns's ties to Ross become public knowledge. Journalists swarm the podium with cameras and questions about Ross's connection to Sterns and the existence of experimental gamma treatments. The scrutiny, the accusations, and the recollection of violence all combine to inflame Ross's physiology: decades of gamma saturation in his bloodstream, coupled with surging stress hormones, push Ross beyond human control. His skin reddens, his muscles bulk grotesquely, and he transforms into a towering crimson creature--Red Hulk--shattering the press conference.

The Secret Service opens fire and naval helicopters attempt to subdue him with missiles, but Red Hulk plucks a missile from the air and smashes two incoming choppers aside with destructive swipes. He storms from the White House grounds into nearby areas, battering structures and tearing at anything that stands between him and escape. Captain America intercepts him. Sam uses his shield, his flight systems, and close-quarters tactics in a protracted confrontation that tears up parts of the White House grounds and causes structural damage to the Executive Mansion itself. Red Hulk grabs and hurls vehicles, and at one point rips Sam's wings from his suit, shredding fabric and electronics. Sam endures bone-jarring blows while attempting to keep Red Hulk from leveling the building entirely.

Instead of matching brute force with force, Sam chooses to speak. He lures Ross--still inside the monstrous form--toward the cherry blossom trees in Washington, D.C., where Ross used to visit with his daughter Betty. While the creature howls and attacks, Sam absorbs a massive blow by planting his shield and letting the impact surge through it. He rolls back to his feet amid splintered petals and keeps talking, addressing Ross's name, referencing the small, private memories he knows about Betty and Ross's visits under those trees. The invocation of those personal recollections reaches whatever remains of Ross's human consciousness. The red skin and the towering frame begin to recede; Ross's expression shifts, his posture collapses, and he transforms back into the man at the center of the crisis. Authorities move in and several agents place Ross in custody as he weeps and surrenders.

After the incident, government investigators review Ross's medical records and the chain of custody regarding Sterns and the pills. Isaiah Bradley is exonerated and released from custody; at a small gathering outside the rebuilt portions of the White House, he reunites with Sam, and they exchange a cautious, meaningful handshake that signals restored trust. The White House begins repairs and the proposed adamantium treaty moves forward with widened scrutiny and supervision. Ross, publicly resigning the presidency, arranges to be incarcerated at the Raft, a high-security facility for superhuman prisoners. Betty Ross visits him there; their exchange is tense and emotionally fraught, with Ross accepting his responsibility and Betty confronting him for years of absence.

Sam visits Joaquin at the hospital while Joaquin recovers from his critical injuries. Joaquin, breathless and bandaged, tells Sam that witnessing Sam's courage is what inspired him to become a hero. The conversation is interrupted by Sam's visit to the Raft, where he sees Ross behind glass. Ross sits subdued and old in the facility cell; he accepts that he must answer for his actions and the consequences of seeking lifelines that corrupted his physiology and judgment.

In a post-credits scene, Sam goes to The Raft to confront Sterns once more. Sterns, now incarcerated but still menacing in his intellect, speaks calmly to Sam. He reveals that he has run probabilistic calculations and perceived patterns beyond Earth: threads that suggest attacks may come from other worlds and universes. He issues this warning not with a threat but with the clinical certainty of someone who believes he can predict future contingencies. Sam listens, the weight of new responsibilities settling over him. The camera lingers as Sterns's words hang in the air, leaving the global landscape altered: Ross is confined, Isaiah free, Joaquin recovering, the treaty negotiated, and Sam Wilson standing at the threshold of a renewed but uncertain role as Captain America and a potential leader of new champions. The story ends with Sam absorbing Sterns's warning and looking out over the Raft's gray corridors as the screen fades to black.

Without specific details from the movie, this hypothetical scenario provides a general framework for how the ending might be structured. For precise details, one would need to watch the film or rely on detailed reviews or summaries.

There is no detailed information available in the provided search results regarding specific character deaths in the movie "Captain America: Brave New World" (2025). The plot involves Sam Wilson (Captain America) dealing with international incidents and leadership challenges, but it does not explicitly mention character deaths. If you are looking for specific details about character deaths, it might be necessary to consult more detailed reviews or summaries of the movie.

Here is a summary of what is known about the plot:

• Plot Overview: The movie follows Sam Wilson, the new Captain America, as he navigates international incidents and leadership challenges. He is tasked with stopping the illegal sale of classified items and later becomes involved in a summit discussing a new metal, presumably adamantium. The plot thickens with a mysterious incident at the White House involving mind control or manipulation, but no specific character deaths are mentioned in the available information.

Without access to more detailed information or specific reviews that discuss character deaths, it's not possible to provide a list of characters who die in the movie.

Yes, Captain America: Brave New World (2025) does have a post-credits scene. In this scene, Sam Wilson meets Samuel Sterns, also known as the Leader. The Leader indicates that he has deduced future conflicts by "reading the probabilities" and warns Sam Wilson about impending threats, stating, "we'll see what happens when you have to protect this place... from the others." This warning could either hint at a multiverse threat or a conflict with other groups, such as Bucky and Yelena's New Avengers, rather than a traditional multiverse war.

Sam Wilson struggles with the burden of leadership and the legacy of Steve Rogers while navigating dangerous missions without superpowers. He also faces a global conspiracy involving a newly discovered metal, adamantium, and must work with a government he is wary of, including President Thaddeus Ross, who has his own agenda.

Sam Wilson mentors Joaquin Torres, who takes on the mantle of Falcon. Sam is hesitant to involve Torres in dangerous missions due to their lack of superpowers, but they work closely together on recovering stolen adamantium and training with Isaiah Bradley, a former super soldier and mentor to Sam.

Isaiah Bradley is a former super soldier who was imprisoned and experimented on by the U.S. government. He serves as a mentor to Sam Wilson and Joaquin Torres. During a summit at the White House, Isaiah is involved in a mysterious attack on President Ross and is subsequently captured and imprisoned, which raises questions about the conspiracy at play.

Adamantium is a newly discovered metal found on 'Celestial Island' formed by the Celestial Tiamut. It is highly valuable and versatile, leading to international tensions. President Ross proposes a treaty to govern its mining and distribution to avoid an arms race. The illegal sale and theft of adamantium samples drive much of the film's conflict and intrigue.

President Thaddeus Ross is portrayed as a complex figure who seeks to reform the Avengers and control the distribution of adamantium through a treaty. However, his intentions are questioned after an assassination attempt occurs during a summit he hosts, involving people under mysterious influence. His relationship with his estranged daughter and his past add layers to his character, creating tension and uncertainty about his true motives.
