It's not original or creative if you don't come up with it yourself.Here's some advice:Take out a piece of paper and jot down EVERY idea that comes to mind. You can also write down your favorite parts of stories you read or movies you watched. After you are done, circle the ideas that you think are necessary in your story, or the ideas you like, and cross off the ones you don't. Then try putting the ideas together. You may need to change or add some things to do this, but when you are done you may have your story.I'm sorry I can't be more help, but you have to come up with this on your own.
