Plot Points by Act
Act I
SetupStatus Quo
Seth Brundle, a brilliant but socially awkward scientist, meets journalist Veronica Quaife at a press event. He's isolated, obsessive, and lacks human connection despite his genius.
Theme
Brundle tells Veronica: "I'm saying I'm an insect who dreamt he was a man and loved it. But now the dream is over and the insect is awake." (Stated in reverse - the film opens with this thematic DNA about humanity vs. the primal self).
Worldbuilding
Brundle brings Veronica to his warehouse lab and reveals his telepods - devices that can teleport matter. He demonstrates with her stocking, then a baboon (which turns inside-out horrifically). We learn he can't teleport living flesh successfully yet. Veronica wants to document his work.
Disruption
Brundle successfully teleports a second baboon intact and alive. The breakthrough works - living flesh can now be transported. This success opens the door to human teleportation and changes everything.
Resistance
Brundle and Veronica begin a relationship as she documents his experiments. They grow intimate. Her editor/ex-boyfriend Stathis interferes. Brundle becomes more human through love, learning about the "flesh" - sensuality, connection, jealousy. He debates whether to teleport himself.
Act II
ConfrontationFirst Threshold
Drunk and jealous after seeing Veronica with Stathis, Brundle impetuously decides to teleport himself. He enters the telepod alone - unaware that a housefly has entered with him. He initiates the sequence, crossing the point of no return.
Mirror World
Brundle emerges from teleportation feeling incredible - stronger, more confident, sexually potent. Veronica becomes his mirror, representing pure humanity and love. Their deepening relationship will contrast with his coming transformation.
Premise
The "promise of the premise" - watching Brundle's transformation. He displays superhuman abilities: gymnastics, strength, sexual stamina. But disturbing changes emerge: coarse hairs, skin lesions, strange eating habits. Veronica grows concerned. Brundle becomes erratic, aggressive. He discovers via computer that the teleporter fused him with the fly at molecular-genetic level.
Midpoint
Brundle realizes the horrible truth: "I'm saying... I'm saying I - I'm an insect who dreamt he was a man and loved it. But now the dream is over... and the insect is awake." He understands he's becoming Brundlefly - a fusion creature. The false victory of successful teleportation is revealed as ultimate defeat.
Opposition
Brundle's transformation accelerates horrifically. Body parts fall off; he vomits corrosive enzymes to digest food externally. He becomes "Brundlefly" - more insect than human. He tries to accept it, then tries to reverse it. Veronica discovers she's pregnant with his child. Brundle's humanity slips away as the insect nature takes over. He kidnaps Veronica, planning to fuse himself with her and the unborn child.
Collapse
Brundle's last human remnants - his ears, remaining teeth, his entire human face - fall away, revealing the full insect underneath. Seth Brundle as a human being dies; only Brundlefly remains. "What am I? I'm saying... I'll hurt you if you stay."
Crisis
Brundlefly prepares his final desperate plan: to fuse himself with Veronica and their unborn child in the telepods, hoping to dilute the fly genes and become more human. Veronica and Stathis are trapped in the warehouse. The creature that was Seth acts on pure instinct now.
Act III
ResolutionSecond Threshold
Stathis arrives with a shotgun. The final confrontation begins. Brundlefly drags Veronica to the telepods to execute his fusion plan - but a fragment of Seth's consciousness remains, setting up the final tragic choice.
Synthesis
Brundlefly battles Stathis (dissolving his hand and foot with vomit-enzyme). Veronica escapes the telepod. Brundlefly enters alone, but the damaged telepod fuses him with its metal parts, creating a grotesque fly-human-machine hybrid. The last spark of Seth's humanity emerges: he takes Veronica's shotgun and places it to his own head, begging her to end his suffering.
Transformation
Veronica, weeping, shoots Brundlefly in the head, granting him the mercy of death. The final image: the creature's suffering ends. In contrast to the opening's brilliant, isolated scientist, we end with a merciful killing - love expressed through release. Transformation complete: from man to monster to memory.
