It's Wikipedia that has the right plot. There is a young girl (different actors, ages, & genders) who wants to have a child and she manages to get pregnant. Her parents force her to have an abortion and she runs away. She gets a trucker to drive her and they have sex that night but he abandons her in the morning.
Then comes the "special world" -- she is found by a young boy who invites her to his home which is a massively Christian orphanage for disabled and orphaned kids. The kids dance and sing and have CDs out and are completely dominated by Mrs. Sunshine. The girl overhears that the father kills abortion providers and will kill the one who did her abortion. The person who actually does the killing turns out to be the trucker in a different name.
She makes sure she goes with him to the shooting but he is very upset when he kills not only the doctor but one of his kids. When the police show up at the motel, he purposely answers the door with a shotgun and is killed.
She goes back to her family, but has sex with the same person who got her pregnant the first time.
That's not a special world, that's an introduction to a Christianity that wants to keep babies from being aborted and at the same time, kill the abortion providers -- all wrapped in nice smiley kids.
The palindromes come from names -- Aviva, Bob, Otto -- and the story arc -- sex, pregnancy, Christianity, sex.
The Christian part was just so saccharine that even though it's meant to show you the division of their views, I really didn't like it.
