Bugonia, Yorgos Lanthimos’s 2025 remake of the Korean film Save the Green Planet!, ends by confirming that the kidnapped pharmaceutical CEO Michelle Fuller (Emma Stone) really is an alien, and that she decides to wipe out humanity. Teddy (Jesse Plemons), the beekeeper conspiracy theorist who abducted her, was right about her and dies anyway.
Spoiler warning: this Bugonia ending explained FAQ gives away the full final act, including the twist and the last scene.
The short version: Teddy blows himself up in Michelle’s office closet; Michelle walks back into that closet, is beamed to her ship, and pops a bubble over a model of Earth, killing every human at once. The film then shows people dead where they stood while animals carry on. Lanthimos, Stone and screenwriter Will Tracy have all described the ending as hopeful, though, as Tracy put it, it was built to support more than one reading.
Bugonia ending explained: what happens in the final act
The last act turns on a lie that is also the truth. Teddy has learned that his mother Sandy (Alicia Silverstone) fell into a coma after a clinical trial run by Michelle’s company, a trial Michelle personally oversaw. Michelle, held in his basement with her head shaved, finally tells him what he wants to hear: she is an Andromedan, and the antifreeze in his car will cure his mother. He feeds it into Sandy’s IV, and she dies.
Michelle then tells him her people have been shaping humanity since the age of the dinosaurs and that her mothership will be in reach during an upcoming lunar eclipse. She leads him to her office, where, she says, the closet is a portal. Teddy steps in wearing a suicide vest “for insurance,” in Inverse’s summary, and the bomb goes off, killing him and knocking Michelle unconscious.
She wakes in an ambulance, escapes, returns to the wrecked office and steps into the closet. It works. On a goopy ship bridge, the Andromedans greet her as their ruler. Asked whether Earth is worth saving, she pops a bubble over a model of the planet, and every human dies instantly. The final montage shows people around the world stopped mid-task, which Den of Geek lists as everything from mowing the lawn to eating breakfast to having sex.
Is Michelle really an alien?
Yes. The film spends nearly two hours letting you suspect Teddy is a delusional man who has kidnapped an innocent executive, then confirms almost everything he believed. Den of Geek notes that even his wildest ideas check out: Michelle’s long red hair is how she talks to the mothership, which is why Teddy shaved her head. His one mistake, as Den of Geek puts it, is not realizing that Michelle “is the actual Andromedan empress” rather than a lower-ranking agent.
The twist is inherited. In Jang Joon-hwan’s Save the Green Planet!, the abducted CEO is likewise revealed to be an alien, and he likewise returns to his ship and orders Earth destroyed, disgusted with the “failed experiment” of humanity, as Inverse describes it. Tracy told Inverse there was never a fallback: “There was never really a discussion about changing the ending or having a backup ending.”
Why do the animals survive?
This is the change Tracy cares about most. In the 2003 film, a light sweeps over people around the world and finally over an abandoned dog before the whole planet explodes. In Bugonia, Den of Geek points out, the dogs do not die; only humans are switched off.
Tracy explained the difference to Den of Geek: “The aliens in that film kind of threw the baby out with the bathwater,” he said. “In this film, they just kind of turn off all the humans. We just fall asleep like robots forever, and we’re just gone.” Because the bodies stay in frame, he said, the closing tableau becomes a record of people at their best, worst and silliest: “You see everything we’d be losing, good and bad, without us.”

Is the Bugonia ending hopeful or bleak?
The people who made it lean hopeful. “I think it’s hopeful,” Lanthimos told Business Insider. “I think even if it’s quite sad, it allows for some hope to start again, in a way, and maybe make things better.” He said he wanted the death montage to be “gentle and human” and avoided “a bombastic kind of ending.” He has also heard both reactions: “A lot of people think the ending is very hopeful, and there are people who think it’s very bleak.”
Stone told Gulf News the ending moves her for the same reason: “It brings me to tears when I see the end because I feel so hopeful and such peace.” She added that Patti Smith had the opposite response: “She said she was devastated.”
Tracy’s version is a warning rather than a prophecy. “A really bleak ending would be saying, ‘Well, it’s always going to be like that,’” he told Den of Geek, arguing that the point is the opposite: “If we don’t want that kind of ending for ourselves, then we have to start listening to each other.” He told Inverse the ending reflects “a very specific kind of political turn and hopelessness that we’re feeling at the moment.”
What about that song over the final montage?
The closing images play under Marlene Dietrich’s recording of “Where Have All the Flowers Gone?” Not everyone liked it. NPR’s Glen Weldon, who enjoyed most of the film and called the final act “kind of hilarious,” singled out those “last three minutes and 37 seconds” as the problem, objecting that Lanthimos lets the song play “in its entirety, all five verses.” He reported that several viewers he spoke to liked the film but disliked the ending, and that the distinction worth asking about is whether they mean the twist or the montage.
What does the title Bugonia mean?
The title came from Lanthimos. “It was Yorgos who suggested Bugonia,” Tracy told Inverse, describing it as “a Greek myth about a colony of bees that spontaneously arises from the corpse of a cow.” The myth fits Teddy, a beekeeper, and it fits the ending: new life from a carcass, a world that carries on after its dominant species is gone. If you came to the film from Lanthimos and Stone’s previous collaboration, our Poor Things runtime and versions guide covers that one.
