Luther Manning is a corporate trainer, married to a woman with a
son from a previous marriage. After he gets a big promotion at work,
they go out to celebrate. But the evening ends badly when they are
involved in a bad car accident. Luther suffers horrible dreams and
wakes in a hospital. He is discharged shortly, but isn't quite himself.
He is having terrible pains, weird lumps form under his skin and his
hearing seems to becoming hypersensitive. Frightened, he heads back to
the hospital to see the doctor who treated him. The hospital has no
idea who this doctor is and has no record of Luther being a patient.
Paranoia quickly starts to set in with Luther.
What has happened is that the crash was no accident. A secret government agency deliberately crashed into Luther so that they could use him as a guinea pig in their nanotechnology experiments. The agency has been testing this project on volunteers from the military but wants to know what happens to a normal man. The nanotechnology basically starts to rebuild Luther from the inside out. He now has a computer wired into his brain, liquid metal armor that can appear when needed, greatly improved vision and hearing and the ability to generate weapons pretty much out of thin air. More here.
I can see what the National Nanotechnology Initiative is worried
about. There are kids out there who will mistake this for a documentary
and get the wrong idea about real nanotechnology.
