The film opens amid chaos aboard a commercial airliner, where a violent melee erupts between numerous assassins and terrified passengers. The conflict escalates when one assassin fires a bullet through a window, causing rapid depressurization that violently ejects several people from the plane as it begins to plummet. This intense scene immediately sets a high-stakes tone, plunging viewers into a deadly game of survival at 30,000 feet.

Twelve hours earlier in Bangkok, CIA Agent Aaron Hunter uncovers disturbing intelligence: a shadowy terrorist known only as "The Ghost" has successfully dismantled a covert CIA operation. Hunter wishes to keep this information contained, but CIA Director Katherine Brunt learns of the threat and declares The Ghost a top national security priority. With no available field agents nearby, Brunt reluctantly turns to Lucas Reyes, a disgraced former Secret Service agent who has been stranded in Bangkok for two years after Brunt herself placed him on a no-fly list. Lucas, embittered by their past and the betrayal that led to his downfall, initially refuses her request.

Despite his defiance, Lucas's resolve weakens after a violent encounter with local thugs at a bar. He contacts Brunt, who offers him a new passport and the chance to clear his name if he can locate The Ghost and bring her to San Francisco. Lucas begrudgingly accepts the mission and heads to the airport. Unbeknownst to him, the flight he boards is already a powder keg: a $10 million bounty on The Ghost's head has attracted a swarm of assassins, each intent on claiming the prize.

Once airborne, Lucas strikes up a conversation with a fellow passenger named Cayenne, who appears friendly but soon reveals sinister intentions. Cayenne drugs Lucas with a powerful sedative in the airplane restroom, hoping to incapacitate him. Lucas narrowly escapes death by using his strength to push Cayenne into the ceiling sprinkler, which impales Cayenne's head. Regaining his composure, Lucas alerts Brunt to the deadly situation unfolding onboard.

Flight attendants Isha and Royce become aware of the escalating violence. When they confront Lucas, he fights back, revealing the true danger aboard the plane. Lucas soon deduces that Isha, the seemingly unassuming flight attendant, is in fact The Ghost. He notices her cold sweats and a wound reopening, signs of the pressure she is under. Isha reluctantly allies with Lucas, recognizing that their survival depends on cooperation as assassins close in from all sides.

As the battle intensifies, the film reveals Isha's harrowing backstory. Once a trafficked child forced into technological crimes by her captors, she escaped and developed a sophisticated device containing incriminating data on global criminal networks, including corrupt elements within the CIA. This device is the true prize everyone aboard the plane seeks. Isha's motivations extend beyond mere survival; she fights to expose and dismantle the criminal enterprises that enslaved her and others.

Lucas's own past is gradually unveiled. He was once a Secret Service agent who lost everything after killing a diplomat who abused young prostitutes. The diplomat was the brother of the CIA's Deputy Director, and Brunt, who had been romantically involved with Lucas, betrayed him to protect her career. This betrayal fuels Lucas's deep mistrust of Brunt and complicates his mission.

The assassins aboard the plane are a diverse and deadly group, including a Sikh man ruined by cryptocurrency losses linked to The Ghost, a female assassin who attacks Lucas but is killed when he jams a broken wine glass into her eye, and a trio from a group called Thai Wan Deng. Lucas dispatches them all in brutal hand-to-hand combat, even as his own image and bounty are broadcast to every assassin onboard, making him a target as well.

Brunt, monitoring the situation from the ground, reveals that Hunter has been manipulating events. Hunter orchestrated the assassination attempts on both Lucas and Isha to eliminate them and seize the device for himself and Brunt's shadowy organization. When the plane's pilots are killed during the chaos, the aircraft's stability deteriorates further. The hull is breached, causing more passengers to be sucked out, and the plane begins a dangerous descent.

In a desperate gambit, Lucas takes what he believes is adrenaline but is actually a hallucinogenic drug, which propels him into a frenzied state. Alongside Isha and an ally named Master Lian--a passenger who leads a group of fighters--they engage in a bloody melee against the remaining assassins. The fight spills through the cabin, with Lucas wielding a pickaxe and Isha using her combat skills to mow down enemies. Despite their efforts, Master Lian and her students are killed, and the plane's condition worsens.

On the ground, Brunt grows impatient as the plane fails to land in San Francisco as scheduled. She executes Hunter with a bullet to the back of the head, blaming him for the failure. Meanwhile, Lucas and Isha reach the cockpit, where Isha reveals that the device she carries has been piloting the plane autonomously, her true escape plan. Lucas refuses Brunt's demands to hand Isha over, lying about having seen the device and signaling his intent to expose Brunt's corruption.

The film closes with Lucas passing out from his injuries. He awakens in a war-torn hospital, where Isha informs him that their mission is far from over: they must now rescue trafficked children caught in conflict zones. Lucas's weary but determined response, "Oh, fuck!" underscores the beginning of a new, perilous chapter.

Throughout the film, the narrative weaves intense action sequences with character-driven revelations. The confined setting of the airplane amplifies the tension, forcing Lucas and Isha into an uneasy alliance against overwhelming odds. The political intrigue involving Brunt and Hunter adds layers of betrayal and moral ambiguity, while the personal histories of Lucas and Isha provide emotional depth. The film's climax combines brutal combat, technological twists, and shifting loyalties, culminating in a resolution that sets the stage for future missions beyond the immediate survival struggle.

At the end of Fight or Flight (2025), Lucas and Isha, after battling assassins aboard the plane, reach the cockpit only to find the pilots dead. The plane misses its San Francisco landing, leading to Brunt killing Hunter for failure. Brunt tries to coerce Lucas to betray Isha, but Lucas refuses. Isha reveals the plane was being piloted by a supercomputer all along, which was her true escape plan. Lucas then passes out from his injuries. He later wakes up in a war-torn hospital where Isha tells him their fight is not over.

The ending unfolds with intense, detailed scenes aboard the commercial airliner. Lucas and Isha, having fought off numerous assassins using improvised weapons and martial arts, finally make their way to the cockpit. The atmosphere is tense and chaotic; the plane's hull has been ruptured during the fight, causing structural damage and decompression. Both pilots lie dead, victims of the violent struggle.

As the plane approaches San Francisco, it fails to land on time. Katherine Brunt, a shadowy government agent who had recruited Lucas, grows furious at Hunter, another agent who had kept critical information secret. Brunt kills Hunter in a cold, decisive moment, blaming him for the failure.

Brunt then confronts Lucas, attempting to force him to hand over Isha, who is revealed to be "The Ghost," a mysterious figure possessing a supercomputer capable of hacking any encrypted system. Lucas, despite his injuries and exhaustion, refuses to betray Isha, showing his loyalty and resolve.

Isha then reveals a crucial secret: the supercomputer she carries has been piloting the plane autonomously the entire time, which was her real plan to escape. This revelation shifts the understanding of the entire flight's events.

Lucas, gravely wounded, loses consciousness. The scene cuts to him awakening in a hospital ravaged by war, with Isha urgently telling him that their mission and struggle are far from over. The ending leaves the story open, emphasizing ongoing conflict and unresolved danger.

This sequence highlights the characters' resilience and the high stakes of their mission, with the confined, high-altitude setting intensifying the drama and action.

There is no post-credit scene in the 2025 movie "Fight or Flight." The film ends with a cliffhanger, where the main character, Lucas, wakes up in a makeshift hospital room in a building under siege after a chaotic flight. The final lines of the movie provide a comedic tone, with no indication of a sequel via a post-credit scene.

Isha's motives are rooted in her past as a trafficked child and slave; she uses her skills to help free other child laborers, which drives her actions during the flight and confrontation with assassins.

The Ghost possesses a supercomputer capable of hacking any encrypted coding, making it a powerful asset that the antagonists want to secure to increase their app company's power. This supercomputer is central to the conflict and is revealed to have been piloting the plane during the climax.

Lucas Reyes, initially tasked with finding the Ghost, ends up bonding with Isha and fighting alongside her and allies like Master Lian and her students to fend off assassins on the plane. Despite being drugged and injured, he refuses to betray Isha and helps her survive until the plane crash.

The main antagonists include Katherine Brunt and Hunter, who are part of a government sect operating through a social media app. They seek the Ghost and her supercomputer to gain power for their company, leading to deadly confrontations on the flight.

During the climax, the plane's hull is ruptured in the fight, causing it to descend and level out but miss its San Francisco landing. Both pilots and several allies, including Master Lian and her students, are killed. Lucas and Isha survive but the plane crashes, setting up the continuation of their struggle.
