A frozen crevasse yawns open on the ice world Niflheim as the film begins. Mickey Barnes, cold and bloody, lies half-buried on a ledge after falling from a great height. His partner Timo appears above him on the ridge, watching. Timo retrieves Mickey's flamethrower from below but deliberately does not haul Mickey up; he tells him with a shrug that this is the seventeenth iteration and that it is likely the end for this body. A huge native creature slides up out of the snow toward the fissure as Mickey's voiceover confesses that he hates dying.

The narrative then moves back more than four years, to Earth, where Mickey and Timo are on the run from a violent loan shark, Darius Blank. To escape Blank's reach, the two sign onto an off-world colonization program bound for Niflheim. The expedition is led by charismatic politician Kenneth Marshall, who arrives with the performative confidence of a celebrity and a devoted following. Marshall and his wife, Ylfa, establish strict rules aboard the colony ship and later at the surface compound. Timo trains as a shuttle pilot, while Mickey volunteers as an Expendable: a role that sends him on lethal field missions in which his death triggers the colony's cloning printers to reprint him with restored memories. The Expendable program is controversial; the public knows that successive reproductions preserve the person's personality and knowledge, and that dying in the field is an occupational hazard.

Once the convoy reaches Niflheim and the colony begins to probe the planet's ecosystem, the ship's scientists iterate through many printed copies of Mickey to develop vaccines against native pathogens. During this time Mickey develops a romantic relationship with security agent Nasha Barridge. They repeatedly breach Marshall's ordinance banning sexual relations among colonists, slipping away from the strict, rationed communal lunches where food portions are monitored and penalties are enforced. In quiet moments, Mickey tells Nasha that he carries guilt from childhood -- he believes he pushed a button that caused his mother's car to crash and burn -- a private confession that haunts him between missions.

On his fourth year as the seventeenth printed copy, Mickey joins a field team ordered by Marshall to capture and retrieve a native lifeform that the colonists call "Creepers." The expedition consists of Mickey 17, Timo, and two other agents: Kai Katz and Jennifer Chilton. They lower into a crevasse to pursue a nest of the pale, caterpillar-like creatures. Jennifer fires at a small Creeper from above; her shot destabilizes the ice and the ceiling collapses onto her, pinning and crushing her beneath tons of ice. The collapse sends reverberations of horror through the team; Kai is devastated by the loss. Mickey tumbles farther into the fissure; small Creepers swarm around him and he expects to be torn apart. Instead the giant mother Creeper appears and, using her tail, pushes and lifts Mickey out of the crevasse. The creatures do not eat him; they help him to the surface and carry him out like a burdened animal would carry a wounded pack member. Mickey walks back to the compound bewildered, carrying the knowledge that the Creepers behaved kindly toward him.

When he returns to his quarters he is stunned to find another iteration of himself already printed: Mickey 18 is awake and moving through the complex. The colony treats multiples as an unforgivable breach of law -- doubles were banned after a notorious criminal, Alan Manikova, exploited the printer to create copies of himself to commit murders while preserving an alibi. Marshall has publicly sworn that anyone found to have Multiples will be executed permanently. Mickey 17 panics because two active copies of the same person mean certain death for both. Mickey 18, by temperament colder and angrier, immediately goes after Mickey 17 in a bid to eliminate the duplicate. The two hide from security when Marshall and Ylfa enter the quarters; their presence forces both to suppress immediate violence.

Marshall hosts a public dinner with loyalists and visiting scientists to console the expedition for Jennifer's death. Arkady, the lead scientist, secretly laces the meal with an experimental growth hormone. During the dinner Mickey suffers a violent reaction to the drug and then to pain medication intended to calm him. His body convulses and the staff rushes him away. Kai accompanies Mickey to her quarters, ostensibly to sober him and to express her sympathy for losing Jennifer; she attempts to seduce him but he flees back into Nasha's arms. Nasha already knows about the Multiples and initially treats the presence of two Mickeys as something thrilling. Kai discovers the truth about the duplicates and considers reporting them; she later suggests to Nasha a shared arrangement involving the two Mickeys, an idea that disgusts Nasha.

At a ceremonial event where Marshall unseals a large black Niflheim stone as part of his political theater, the ground splits and two tiny Creeper babies erupt from inside the rock: Luko and Zoko. Panic grips the crowd. Security opens fire at the emergent infant creatures. One baby, Zoko, is shot dead by security when it lurches toward the audience; the other, Luko, is captured and hauled away to be displayed as evidence of the threat the natives allegedly pose. Amid this chaos Mickey 18 attempts to assassinate Marshall from the crowd and grazes Marshall's cheek with a grazing shot, but he is stopped and the attempt fails. The Multiples are exposed in the wake of the disturbance; colony security arrests Mickey 17, Mickey 18, and Nasha. In captivity their cages become conversation booths where they recount what happened in the crevasse and Mickey 17 explains that the Creepers saved him. Nasha starts to understand that the Creepers are sentient and not the lethal monsters Marshall portrays.

Back in the compound, Marshall orders Dr. Arkady and other technicians to purge Mickey 17's backup memory files, ensuring that if 17 is killed he cannot be reprinted again. The moral penalties for Multiples are absolute: those convicted are to be annihilated without the chance of reprinting. Meanwhile the Mother Creeper and thousands of her species raise a chorus at the edge of the colony, calling to reclaim the captured baby. The Mother and her swarm surface because Zoko is dead and Luko has been taken; the whole Creeper community comes up to demand restitution.

Darius Blank's influence reaches into the colony. An associate of Blank is in the compound and he orders Timo to kill Mickey and to provide video proof of the dismemberment as proof of completion. Timo arrives at the brig with a blade to dismember Mickey 17; Mickey refuses to permit this. Mickey 18 volunteers to take 17's place in the grisly tableau to distract Timo. The substitution is a ruse: while Timo focuses on 18, Mickey 17 and Nasha use the distraction to subdue and render Timo and Blank's man unconscious. They overpower the would-be executioner and escape their cells. The three of them -- Mickey 17, Mickey 18, and Nasha -- return to confront Marshall just as he prepares to deploy a newly developed nerve agent, Arkady 3.0, intended to annihilate all Creepers on the surface.

Ylfa, meanwhile, keeps a grotesque interest in the Creeper bodies. She orders that the captured Luko have his tail cut off in the lab to produce a new taste product she hopes to commercialize; the tail cut is performed in a sterile room as if it were a culinary experiment, and one of the agents, Zeke, reaches to help Nasha and gets his hand sliced. He pulls back bleeding, shaken, and later reveals to Nasha and others that he and several security staff have compiled incriminating recordings of Marshall and Ylfa's abuses. Those recordings form leverage against the Marshalls.

Marshall announces to the compound that the two Mickeys will be marched out into the snow and forced to compete for Creeper tails. Each Mickey will be fitted with a remote-detonated explosive vest; the charged dead weight will prevent escape. The one who returns with the least will be detonated by Marshall, a public demonstration of authority and intimidation. The Mickey pair step, guided by Nasha and under watchful crowd eyes, into the white wasteland toward the Mother's horde.

Before the competitive hunt begins, a sympathetic scientist slips a translation device to Mickey 17; the wearable allows him to parse the clicks and calls of the Creepers into phrases he can understand. When he approaches the Mother in the swirl of snow and the groaning chants of the swarm, the Mother speaks through the translator. She identifies Mickey by name and explains that the Creepers have dug up to reclaim Luko because another infant, Zoko, has been killed. She issues a single demand: return Luko and offer a human life in exchange for Zoko's death, or the Creepers will exterminate humanity in retribution. Mickey 17 signals toward Nasha with a simple, agreed gesture -- "bring the baby" -- a shorthand they had established earlier. Nasha has been forced to hold a rope between her teeth; Luko hangs hooked over a disposal pit for Expendable bodies, dangling as if in culinary display. Security hesitates when they see the Mother's intent and the gravity of her demand.

Marshall refuses a peaceful resolution. He refuses to accept that the Creepers are a sentient community with claims to their offspring. Instead he storms onto the ice with a crew and a bazooka, intent on killing the Mother and dispersing the horde. He intends to fire the bazooka at point-blank range into the massed creatures. In the melee that follows, Nasha lunges at Ylfa, seizing her and threatening to snap her neck unless the baby is freed. Nasha forces the lab technicians to release Luko and threatens Ylfa at bladepoint while security tries to restrain her. When Ylfa attempts to let Luko fall to his death, Zeke grabs a hand to prevent it and receives a deep cut; blood slicks the snow. At the same instant several security agents covertly move to arrest Ylfa for her documented crimes, acting on the backroom recordings.

Marshall charges into the crowd with his bazooka, firing a blast that would kill the Mother if it connects. Mickey 18 rushes Marshall's armored vehicle in a direct, personal confrontation. He grabs Marshall and, in a final violent act, presses Marshall's own detonator that controls the remote explosive vests. The detonator activates the bomb on Mickey 18's chest and an explosive charge on Marshall's van, detonating both men together. The blast kills Kenneth Marshall and obliterates Mickey 18 in the same instant; the explosion severs Marshall's life and pulverizes 18's body. That sacrificial detonation fulfils the Mother's demand: a human life in recompense for Zoko's death. The Creepers respond by forming shield-like heaps around the Mother and then retreating with Luko back into the ice as the swarm dissipates.

In the aftermath, security teams detain colluding members of Marshall's inner circle. Ylfa is taken away to a psychiatric facility where she is held. In custody she slits her wrists and dies, a final act that removes her from power but also leaves other secrets and manipulations unresolved. Dr. Arkady and other complicit researchers face exposure but many survive the purges and the colony's reordering. Darius Blank's reach is curtailed when an assassin he sends after Timo appears in the compound and tries to kill the pilot; Timo kills the assassin in self-defense and later testifies against Blank, reducing the loan shark's ability to reach into the off-world colony.

Six months pass. Spring arrives on Niflheim and the colony holds a public ceremony that marks a political reshaping: the Expendable program is formally shut down. Nasha Barridge ascends into a leadership position on the colony council, taking power in a measured, accountable role. The colony's public image transitions away from Marshallian spectacle toward governance and restitution. Mickey Barnes, the surviving iteration who is no longer designated merely by number but allowed to reclaim his original name, continues to work with the Creepers to study their life and communicative patterns. He and Nasha remain a pair; their relationship persists through the rebuilding.

On the day the cloning apparatus is to be decommissioned, the colony gathers for a final ritual. The giant printer that produced the Expendables is scaffolded and wired for demolition. Mickey Barnes is given the honor and responsibility of triggering the device's destruction. He walks to the control panel, hands trembling as he sets the charges and arms the sequence. Before he detonates, a private fear flickers through him: he still suffers nightmares in which Ylfa survives and tries to print a new Marshall to reinstate old abuses. He steels himself, commands his hands to steady, and hits the trigger. The machine erupts in a controlled sequence of explosions and collapses into twisted metal and burned circuitry. The film closes on Mickey, standing in the ash and cold-warmed air, watching the printer smolder as he narrates the closure of an era and the beginning of a new governance on Niflheim. The final image is Mickey walking away from the ruined machine alongside Nasha and others, the colony's future now unbound from the Expendable program.

Short, Simple Narrative Ending

Mickey and his allies manage to return the baby creeper to its mother just as the conflict reaches its peak. In a final act of sacrifice, Mickey 18 attacks the expedition leader Marshall, detonating his explosive vest and apparently killing both of them. This fulfills a deal with the intelligent creepers to exchange a human life for the safe return of their baby, ending the immediate confrontation.

Expanded, Chronological Narrative of the Ending

The movie's ending begins with Marshall, the expedition leader, setting up a deadly contest: both Mickey 17 and Mickey 18 are sent out with explosive vests, each ordered to collect a hundred creeper tails to determine who gets to live. Ylfa, Marshall's wife, supports the hunt, interested in using the creeper tails for culinary experiments back at the ship.

Meanwhile, inside the ship, Nasha, the security agent and Mickey's love interest, attempts to change the power dynamics. She confronts Ylfa, choking her with her legs in a bold move to try to rescue a captured creeper baby.

Outside, Mickey 17 encounters the Momma creeper, the leader of the native life forms. He warns her that Marshall plans to gas her kind. The Momma creeper, revealed now to be highly intelligent, threatens to use sonic attacks that could liquefy human brains unless their stolen babies are returned. With one creeper baby already dead, the Momma creeper demands a human life in return for justice.

Mickey 17 communicates with Nasha using a coded phrase, instructing her to bring the surviving baby creeper outside. Nasha manages to get the baby out just as the conflict escalates.

Marshall, wanting to take charge of the situation personally, drives out in a convoy of massive vehicles to confront the Momma creeper. Around this time, the crew aboard the ship begins a mutiny against the political leadership, dissatisfied with their decisions and brutality.

Outside, the creepers rally around their mother, stacking themselves into massive mounds to shield her from Marshall and his soldiers. The atmosphere is chaotic and tense, with both sides preparing for the worst.

As the standoff reaches its climax, Mickey and his allies--now including Nasha--succeed in returning the baby creeper to the Momma. Satisfied, the Momma creeper still demands a life in return for the one lost, honoring the deal.

It is Mickey 18 who steps forward. In a final act of self-sacrifice, he attacks Marshall and detonates his own explosive vest. The explosion kills both Mickey 18 and Marshall, fulfilling the bargain with the Momma creeper and ending the immediate conflict.

With the leadership in turmoil and the crew in revolt, the movie leaves the settlers' future uncertain. The story ends with the alliance between Mickey 17 and Nasha, the sacrifice of Mickey 18, and the fragile peace with the intelligent creepers, all set against the backdrop of corporate exploitation, colonialism, and the struggle for survival on a harsh alien planet.

The movie Mickey 17 (2025) does not have a post-credits or mid-credits scene. Viewers can leave the theater as soon as the movie ends without missing any additional footage.

Instead of a post-credits scene, the film concludes with a significant ending sequence where the title "Mickey 17" flickers between "17" and "18," then changes to "Mickey Barnes," symbolizing the protagonist's journey toward reclaiming his identity and selfhood. This transformation is part of the film's thematic closure rather than a separate scene after the credits.

Mickey 17 and Mickey 18 are clones of the same man but have distinct personalities: Mickey 17 is good-natured and people-pleasing, while Mickey 18 is arrogant and aggressive. After Mickey 17 survives a mission and returns unexpectedly, violating the rule against multiples, the two initially face conflict, with Mickey 18 attempting to kill Mickey 17. They eventually agree to secretly rotate duties and deaths to survive, navigating a tense coexistence marked by rivalry and reluctant cooperation.

Mickey 17 develops a romantic relationship with Nasha, a brave and loyal security officer. Their bond grows despite the harsh conditions on the ice planet Niflheim and the political tensions aboard the ship. Nasha supports Mickey 17 in critical moments, including during conflicts with other characters and the dangerous missions. Their relationship adds emotional depth and personal stakes to the story, contrasting with the political and survival challenges they face.

Kenneth Marshall is the expedition leader and a disgraced politician running the mission to colonize Niflheim. He enforces a strict rule that all clone multiples must be eliminated, which creates tension when Mickey 17 and Mickey 18 both exist. Marshall orchestrates brutal contests, such as forcing Mickey 17 and 18 to compete in dangerous tasks wearing explosive vests. He personally leads a convoy to confront the native Creepers, showing his authoritarian and self-serving nature. His political ambitions and harsh decisions drive much of the conflict and danger in the story.

The Creepers are native lifeforms on Niflheim, initially thought to be simple creatures but revealed to be highly intelligent. Mickey 17 is sent to capture them but falls into a fissure and is swarmed by Creepers, who instead of killing him, carry him to the surface. Later, Mickey 17 warns the Creepers' Momma that Marshall plans to gas their kind. The Creepers threaten humans with sonic attacks unless their stolen babies are returned, leading to a tense standoff. Mickey 17 plays a key role in returning a surviving Creeper baby, which is pivotal in the climax and the life-for-a-life agreement with the Creepers.

The film depicts Mickey as an 'Expendable' who dies on dangerous missions and is then cloned through a process called 'reprinting,' which restores his memories. Each iteration, such as Mickey 17 and Mickey 18, retains core memories but develops distinct personality traits, leading to internal conflict and questions about identity and individuality. The existence of multiple Mickeys challenges the mission's rules and raises ethical and existential issues about selfhood and disposability in the context of the colonization effort.
