Oh. He's just this guy, from this movie. These two people die, and become ghosts, and this family moves in-- and the girl's kindof weird. Her family doesn't really get her because she's doing weird girl things like taking polaroids, and her dads trying to make her be all chummy with her stepmom-- and she ends up making friends with the ghosts. They team up with this weird demon-ghost guy, Beetlejuice, to make her parents miserable, but he just fucks shit up. But in like. A funny way.

In the end the girl lives happily ever after with her new ghost parents.
