The Fly

Seth Brundle, a brilliant inventor, reveals his groundbreaking invention, the telepods, at a party hosted by Bartok Industries. These telepods are capable of disintegrating matter, transmitting it across space, and reintegrating it, which excites those present, especially Veronica Quaife, a reporter.

After a fascinating demonstration of the telepods, Veronica convinces her boss, Stathis Borans, to publish the story about Seth’s invention. Despite some doubts, she decides to track Seth's progress as he works on improving the telepods, agreeing to wait on publishing the story.

Seth decides to test his invention by sending a baboon through the telepods. However, the baboon emerges from the reintegration process inside out, which raises concerns about the telepods' safety and reliability.

As Seth continues to work on his telepods, he and Veronica grow closer, eventually confessing their love for one another. Their relationship intensifies, leading to a passionate night together but also igniting Seth's obsession with enhancing his invention.

After a night of drunken celebration, Seth, feeling threatened by Veronica’s past with Stathis, decides to teleport himself out of spite. Unfortunately, he accidentally teleports with a housefly, which leads to an unexpected and dangerous outcome.

Following his teleportation, Seth begins to notice alarming physical changes. He exhibits unusual cravings, unexpected strength, and strange hair growth, which he initially dismisses as positive enhancements until they continue to worsen.

Seth's physical and mental state deteriorates further as he transforms into a grotesque hybrid human-fly creature. He begins to act irrationally, pushing Veronica away and seeking out his primal instincts, which frightens her.

Veronica witnesses the severe deterioration of Seth's condition when she decides to confront him. She comes to understand that he is becoming a monster and realizes the risk she faces in being around him.

Veronica discovers that she is pregnant with Seth's child, a revelation that brings a mix of joy and fear. She confides in Stathis, who cautions her about the potential dangers of returning to Seth in his current state.

In a desperate bid to keep Veronica with him, Seth kidnaps her when she seeks medical help. He believes their unborn child may be the last remnant of his humanity, and he insists she should not abort the baby.

As his transformation completes, Seth becomes a monstrous insectoid creature named 'Brundlefly' and loses all human semblance. He reveals to Veronica his plan to use the telepods to combine their forms, hoping to regain his humanity.

In a climactic struggle, Seth attempts to force Veronica into the telepod to combine themselves. As he loses control, Veronica fights back and accidentally rips off Seth's jaw, which triggers the last stages of his transformation.

Now fully transformed into Brundlefly, Seth pleads for Veronica to end his suffering. Using a claw to point a shotgun at its own head, he silently asks her to kill him, leading to an intense emotional moment.

Faced with the monstrosity that was once her lover, Veronica finds the strength to pull the trigger. The ending is poignant and tragic, as she mourns the loss of Seth and the man he once was.
