Enredo

Two conspiracy-obsessed young men kidnap the high-powered CEO of a major company, convinced that she is an alien intent on destroying planet Earth.

Setup . Teddy Gatz is a beekeeper and former factory/warehouse employee at a pharmaceutical megacorporation called Auxolith. . He believes that chemicals produced by Auxolith are responsible for Colony Collapse Disorder, decimating his bee hives. More deeply, he holds a personal grievance: years earlier, his mother, Sandy, was part of an experimental drug trial run by Auxolith that left her in a persistent vegetative state - mentally incapacitated. . Haunted by loss and engulfed by paranoia, Teddy becomes convinced that the root cause is far worse: he believes the company's CEO, Michelle Fuller (Emma Stone), isn't human - but an alien from the race of "Andromedans," infiltrating powerful positions to manipulate and destroy humanity.

The Kidnapping & Descent . Teddy enlists his cousin Don - neurodivergent and emotionally vulnerable - to help kidnapping Michelle. They break into her home, abduct her, and take her to their rural basement hideout. . As part of their "proof," they shave Michelle's head - believing that only by removing her hair can they prevent her from contacting her alien "mothership." They also cover her body in antihistamine cream (a bizarre ritual) to further prevent her "signals." . Teddy gives Michelle four days to "prove" she is an alien and negotiate Earth's "liberation" before a looming lunar eclipse - which, in his delusion, would allow the Andromedan mothership to enter Earth's atmosphere undetected.

Torture, Collapse & Revelations . Throughout her confinement, Michelle endures psychological and physical torture. Meanwhile, the film intersperses flashbacks showing the tragedy in Teddy's past - especially the experiment on his mother - illustrating how trauma pushed him into fanaticism. . Don becomes increasingly distressed by the violence and guilt. In a moment of despair, he commits suicide in front of Michelle, using a shotgun. This shatters the already fragile dynamic and shakes even Teddy's extremist resolve. . Michelle uses that moment to manipulate Teddy emotionally. She argues that the Andromedan "cure" for his mother's condition is in a bottle disguised as antifreeze in her car. Distraught, Teddy rushes to the long-term care facility and injects it into his mother's IV - killing her. This act of desperation highlights how far his delusions have pushed him.

Final Twist & Apocalypse . Meanwhile, Michelle discovers a hidden room in the basement filled with evidence that Teddy had victimized others before - prior "test subjects." . After Teddy returns, Michelle confronts him. She delivers a shocking confession: the Andromedans did, in fact, exist - they arrived on Earth in ancient times, engineered humanity after a previous extinction, but had grown disillusioned with human cruelty, destruction, and environmental collapse. She claims their "mission" was to save the planet, not destroy it. According to her, humans became the real threat. . She offers to take Teddy to the Andromedan mothership via a "teleportation closet" in her office, hoping to show him their true plan. Teddy, armed with a suicide vest, agrees. He enters the closet - the vest detonates. He dies instantly. At first, it seems Michelle may be the only survivor of this madness. . However - in a final, devastating twist - Michelle escapes the ambulance, returns to her office, and re-enters the teleportation closet. The portal activates: she beams up to the mothership. It's confirmed that she is the Andromedan Empress. Her proof: a control room where she and other aliens oversee Earth's fate. She declares humanity a "failed experiment" and initiates a final cleanse: with a gesture, the mothership triggers a planetary-wide extinction. Instantly, people all over Earth begin dropping dead. . The film ends on a haunting note: all of humanity is wiped out - but in the final image, bees return, suggesting nature may reclaim the planet. The title "Bugonia," referencing a mythic belief of spontaneous generation of bees from a sacrificed ox carcass, serves as a grim metaphor for sacrifice, rebirth, and the destructive consequences of human hubris.
