A brilliant but eccentric scientist begins to transform into a giant man/fly hybrid after one of his experiments goes horribly wrong.
Several months after the events of ''The Fly (1986 film)'', Veronica Quaife delivers Seth Brundle's child. After giving birth to a squirming larval sac, she dies from shock. The sac then splits open to reveal a seemingly normal baby boy. The child, named Martin Brundle, is raised by Anton Bartok, who is the owner of the company which financed Brundle's teleportation experiments and fully aware of the accident which genetically merged Seth Brundle with a housefly. Martin grows up in a clinical environment. His physical and mental maturity is highly accelerated, and he possesses a genius-level intellect, incredible reflexes, and no need for sleep. He knows he is aging faster than a normal human, but is unaware of the true cause, having been told his father died from the same rapid aging disease.
