Hi Farah! You are speaking of the 2005 film, right? Ok... this is what I think might be what you want:
The residents of a futuristic community are told that the outside world has become too contaminated to support life with the exception of an island. Every week, one resident gets to leave the community to live on the island by way of a lottery.
Lincoln, the main character, begins having dreams that contradict what the main community is told. He decides that he needs to escape. There is a moth, an evil scientist, and many human clones that complicate the main character's plan to escape.
As the main character begins to unravel many mysteries, the most shocking one is the secret that the clones hold.
The ending wraps up the destiny of our hero, but could easily lead the viewer into thinking there might be a sequel! :-)
I would build on the bones that I have given you, but there is the summary!
