I'm going to give the whole movie away, so beware...
Spoiler:
Parents lose their kid at age 8 in an automobile accident. They get him cloned by a doctor who approaches them. Kid turns 8, starts seeing things, and develops a 2nd personality altoghter. 2nd personality ends up being the doctors dead son, since he apparently spliced some of his own gene in the parents kid.Kid goes crazy, sees thing. Movie rips off The Sixth Sense + The Omen horribly, and the kid looks like Damian from Children of the Corn.
All that said, avoid the movie.
