Really?  Is there a reason you're writing this story?  I mean, is it an assignment or something?  Because I've often found that the stories you force onto paper (or computer) aren't often very good.  You should write about something that you WANT to write about, something that you have to write (or type) like lightning to make sure you get down everything you want to say.  But, since you asked, I'll do my best: 

*In a world where science has experimented with modifying human beings, a race of elves have been created.  These elves are not the happy, squeaky, cute creatures parents tell their children about during Christmas time, but rather 7-foot tall, long-haired, pointy-eared, black-eyed creatures gifted with super-human endurance and senses.  They can see, hear, feel, taste, and smell better than humans.  Because of their gifts, they are used as bodyguards and laborers.  The only problem is, these elves don't like being servants to normal humans and they're starting to get restless.  In an attempt to domesticate (love that word) the elves, scientists capture a small group, including our main character, and intend to find some way to control their behavior/mind/reflexes (whatever you want). 

And there you have it.  Probably not what you were expecting, eh?
