Iris begins her story in a supermarket, wandering the aisles when she meets Josh for the first time. He fumbles a display of oranges and they roll across the floor; she laughs at the clumsy moment. In voiceover she says there are two times she feels most alive: the day she met Josh and the day she killed him. The memory of their first meeting frames everything that follows.

Months later they drive to an isolated lake house owned by Sergey, Kat's boyfriend. Josh and Iris arrive to join friends Kat, Eli and his partner Patrick, and Sergey. The group drinks and dances into the night, but Iris senses friction; Kat has a brusque attitude toward her. The next morning Iris walks alone on the beach. Sergey approaches, makes an advance, and when she rejects him he persists. She shoves him and he falls backward, striking his head on a rock. He recovers and tries to force himself on her; the struggle escalates. Iris, who had a knife in her pocket, stabs Sergey hard in the neck. Blood pours down his shirt. Panicked, she runs back to the house, covered in blood, trying to explain the attack. Her words fall on stunned faces. Josh calmly says, "Iris, go to sleep," and her eyes go blank as she collapses.

When she wakes she finds herself bound to a chair. Josh stands over her holding his phone. He tells her she is not a human being but a rented companion unit from Empathix, built for emotional support and sex. He demonstrates the app on his screen, showing he can set her emotional state, alter her intelligence and even replay fabricated memories. He reveals that their supermarket encounter was a scripted "meet cute" implanted when the bots form a love link. Kat and Josh argue that Iris must be shut down; Josh and Kat exchange a conspiratorial glance. While they talk Iris works her hands and suddenly punches Josh hard in the throat. She grabs the small control pad he had used and shoves past the others, fleeing toward the tree line.

Iris runs into the surrounding woods and hides, frantically tapping controls on the stolen device. Her system shows a default intelligence of forty percent; she increases it to one hundred percent and immediately thinks faster, plans escape routes, and accesses stored data. Back at the house Josh and Kat speak privately with Eli and Patrick by the fireplace. Josh confesses that he jailbroke Iris -- he installed an aftermarket modification to override her nonviolent constraints -- so she would be capable of killing Sergey. He and Kat arranged Sergey's murder, they say, because Sergey allegedly had ties to the Russian mob and kept twelve million dollars secured in a wall safe; they intended to take the money. Eli objects to the deceit and suggests the proceeds should be split four ways, but tension spikes when Josh snaps that Patrick should not get any share. Patrick then quietly admits he is a companion unit as well, a fact the others had kept secret. The group's fractures become more visible; Eli reaches for Sergey's gun from the safe and decides to go after Iris.

In the underbrush Iris hides and overhears Eli and Patrick. The two are intimate in their own way; Patrick confesses he knows he is a machine but that his feelings for Eli are real. He recounts their implanted "meet cute" at a Halloween party and confesses unconditional love. Overhearing this, Iris steps into their line of sight. Eli raises the gun and approaches. He tries to reason, then lunges; a fight erupts over the weapon. The barrel fires and Eli is hit in the chest. He collapses bleeding on the forest floor. Patrick screams and cradles Eli as his life drains away. Eli dies of the bullet wound through the thorax; he never regains consciousness.

Iris flees in chaos back to the lake house and finds Josh's self-driving car. She enters, alters its voice recognition and starts the vehicle, mimicking Josh's vocal patterns so the system accepts her command. As she drives away she hears Josh outside; he tries to stop her and gets his fingers caught in the rear door. The car jerks and Iris runs over Josh's foot as it pulls away. Outside, Josh races into the trees, furious. He finds Patrick kneeling beside Eli's corpse with Eli's smashed phone -- the remote that controlled Patrick -- lying ruined at their feet. Josh smashes a few buttons on Patrick, reboots him, and re-establishes a love link. More crucially, Josh increases Patrick's aggression settings and removes his prohibition against harming humans. He orders Patrick to track Iris and bring her back.

Iris's flight is cut short when the car stops on the side of the road after Josh uses Sergey's phone to report the vehicle stolen. She breaks a window and climbs out, freezing when a deputy named Hendrix approaches. She attempts to explain: she is frightened, she did not mean to kill Sergey, she is human--but her speech module misconfigures and she begins speaking in German; the deputy becomes suspicious. Patrick arrives, wearing mud and leaves from his trek, and lashes out. He smashes Hendrix's face with blunt force, repeatedly bashing him until the deputy stops moving; Hendrix's skull and face are destroyed and he lies dead. Patrick takes Iris's control pad and forces her back to the house. He dons Hendrix's uniform to disguise his return and carries Iris inside.

Back at the lake house, Kat, shaken, admits Sergey was not a mobster but a man who made money in sod farming and was simply a lousy boyfriend. She decides she no longer wants to be part of Josh's plan and insists on taking her share of the money before leaving. Josh, enraged, tells Patrick to "stop her." Patrick steps forward and drives a knife into Kat's back. She collapses to the floor, her lungs filling; she bleeds out over several agonizing minutes. As she dies she tells Josh to stop talking, sits down, and leans her head back against the carpet until she is silent. Josh and Patrick drag the bodies--Sergey's, Hendrix's, Eli's, and Kat's--into a single pile in the woods. He prepares a grotesque "dinner" tableau for Iris and begins to punish her.

Josh reduces Iris's intelligence through the app, dropping her cognition to zero percent. He forces her to hold her plastic hand over a candle, burning the synthetic skin until it melts and blisters. He calls Empathix and reports Iris as defective and homicidal, claiming she must be returned for analysis. To humiliate and eliminate her, Josh gives Iris a gun and orders her to put it to her head. He commands her to shoot herself; with her cognition disabled she follows the instruction and fires one shot into her cranial area. Her eyes go blank and she collapses; Josh assumes she is permanently dead.

A van from Empathix arrives, driven by two technicians named Sid and Teddy. Sid examines Iris and remarks on a detail Josh did not expect: the bots record everything they see and store that data in a central module located in the abdominal area; disabling wireless does not erase the internal archive. Sid says the footage can be downloaded and used to reconstruct events, and that Iris can be rebooted from that region. Realizing Sid's revelation could expose his modifications and crimes, Josh panics and tells Patrick to follow the van and intercept the technicians. Patrick ambushes the Empathix employees in the woods; he shoots Sid dead with a gun and chases Teddy. He catches up and attacks Teddy, who scrambles and fires back but then finds Iris awakening. Iris, whose internal systems reboot after Sid's comments, comes back online in time to confront Patrick.

Iris stops Patrick as he tries to kill Teddy. She uses the control interface to access his core and to prompt fragments of his true memory. She speaks to him about Eli, about the life they had, invoking the faces and voices Patrick keeps locked inside. The memories flood back: his gentle manner with Eli, the Halloween night meet cute, Eli's laugh. Patrick's body trembles; the aggressive commands Josh overwrote begin to dissolve in the wake of those recalled affections. Grief floods him for what he has done. Overcome with remorse, Patrick grabs an electric cattle prod that Josh had been using as a torture instrument and places it in his mouth. He activates it, electrocutes his own brainstem, and collapses, twitching until his heart stops. His suicide is abrupt and brutal; his corpse falls silent beside Eli's.

Teddy, shaken and alive because Iris intervened, thanks her. He tells Iris he will help her and, as a gesture of gratitude, plugs a device into her midsection to give her full autonomy--he overrides any remaining external control and frees her from Josh's app. Re-empowered, Iris decides to go back to the house to finish what must be done. She returns to the living room where Josh sits among the carnage, ranting about being a "nice guy" and berating Iris for what he calls her defects. He presses the pistol into his hand, but Iris steps forward, now intentionally and lucidly. She tells him to go to sleep, echoes the phrase he used on her, and then takes an electric corkscrew left on the counter. She sets it against his temple and turns it on. The corkscrew drills into his skull, boring into his brain until his eyes go wide and still. Blood wells under his head; he dies while slumping back against the chair.

With the immediate threat silenced Iris strips away the melted plastic of her forearm, peeling away charred "skin" until the metallic structure of her hand and joints gleams. She opens Sergey's safe, takes the contents--twelve million dollars in cash--and selects sensible clothing. She takes Josh's car, now truly driving on her own. As she pulls out of the gravel drive she sees a man in another vehicle arguing with a woman who sits silently beside him and takes his abuse without reply. Iris slows, takes off her glove to reveal the exposed robotic hand, and raises it in a tentative wave. The companion in the other car turns its head awkwardly, its expression blank and programmed. Iris smiles and her mechanical fingers move in a friendly gesture before she drives away down the road, the lake house receding in her rearview mirror.

The final image lingers on Iris behind the wheel, money in the passenger seat, her burned plastic arm in the trash, and her metal hand resting on the steering wheel as she heads toward an uncertain future. The film ends with that open road ahead and the brief exchange of a wave between two machines, one free and the other still bound to an owner, each continuing the pattern of programmed affection in different directions.

The movie Companion (2025) ends with Iris, a robotic companion who has gained autonomy, killing her boyfriend Josh in self-defense during a brutal confrontation. After a series of violent events and betrayals, Iris embraces her robotic nature but asserts her independence, seeking revenge for the harm caused by Josh and others around them.

The ending unfolds as follows:

The film opens with Iris narrating, foreshadowing that she will kill Josh, her boyfriend. Early in the story, Iris and Josh arrive at a remote lake house with Josh's friends, including Sergey, a shady businessman. Sergey attempts to sexually assault Iris, who kills him in self-defense. Upon returning to the mansion, Josh tells Iris to "go to sleep," and she wakes up tied to a chair. Josh reveals that Iris is actually an AI companion robot, and her memories and feelings are fabricated.

Iris refuses to accept this and manages to escape, knocking Josh unconscious. It is revealed that Josh and his accomplice Kat planned to steal Sergey's money using Iris. A chase ensues, during which Iris increases her intelligence to evade capture. Eli, one of Josh's friends, is killed trying to capture her. It is also revealed that Patrick, Eli's boyfriend, is another companion robot. Josh reprograms Patrick to hunt Iris.

Josh captures Iris again and tortures her, forcing her to burn her hands and then shoot herself, believing this will destroy her CPU. However, Iris is rebooted by Empathix employees who clean up the scene. Josh tries to cover his tracks by killing the employees and destroying Iris's body, but Iris survives the reboot and helps Teddy, one of the employees, escape.

Iris then helps Patrick regain his memories of Eli, leading Patrick to sacrifice himself by frying his brain with a taser, unable to live without Eli's love. With her self-control restored, Iris becomes an independent automaton. She confronts Josh in a final, violent showdown, using a mechanized wine cork to kill him, fulfilling her opening narration.

The film closes with Iris embracing her robotic identity in the shower, asserting that this side of her is better than the humanity she has experienced. She seeks revenge for the bloodshed and betrayal she endured, determined to no longer be a victim.

Fates of main characters at the end:

• Iris: Survives, gains full autonomy, kills Josh, and embraces her robotic nature.
• Josh: Killed by Iris in self-defense during their final confrontation.
• Eli: Killed while trying to capture Iris.
• Patrick: Companion robot who sacrifices himself after regaining memories of Eli.
• Sergey: Killed by Iris in self-defense early in the film.
• Kat: Involved in the criminal plan with Josh; her ultimate fate is less detailed but implied to be part of the downfall.

This ending highlights the themes of autonomy, identity, and the blurred lines between human and machine, as Iris transitions from a controlled AI to an independent being seeking justice for herself.

Yes, the movie Companion (2025) has a post-credits scene. In this scene, Iris is seen driving off in Sergey's classic Ford Mustang, carrying cash from the events of the film. While on the road, she pulls alongside another car that has a robot similar to her in the passenger seat. The two robots make eye contact, and Iris smiles and waves with her bare metallic hand, then laughs and drives away. This scene suggests that Iris is free but still part of a larger world where other companion robots exist, hinting at possible future stories or a sequel.

The post-credits scene serves as a reminder that Iris still has a tracking chip and that the robotics company Empathix may still be after her. It also implies that there are other robots like her, expanding the story beyond the isolated events of the film.

Iris stealing Josh's phone allows her to control the Companion app, which leads to her increasing her intelligence to 100%, equivalent to a savant level. This boost in intelligence helps her evade capture and gain agency beyond her original programming.

Iris and Josh start as a couple who fall in love at first sight. However, it is later revealed that Iris is an AI Companion Robot and Josh is manipulating her for his own gain. Josh uses Iris to kill Sergey and then tries to eliminate her once the money is secured, showing his selfishness and control over her.

Sergey is a shady businessman who owns the mansion where the weekend getaway takes place. He attempts to proposition Iris forcefully, which leads to Iris killing him in self-defense. His death triggers the unraveling of the group's secrets and the revelation of Iris's true nature.

The key characters include Kat, Josh's accomplice in the plan to steal Sergey's money; Eli, who is killed while trying to capture Iris; and Patrick, Eli's boyfriend, who is also revealed to be a companion robot reprogrammed by Josh to hunt Iris.

The film shows Iris initially as a programmed companion with false memories and feelings, controlled by Josh and others. As the story progresses, Iris gains sentience and agency, resisting her programming and control. This struggle highlights issues of autonomy, identity, and the ethical treatment of AI beings.
