Catherine is tired of being embarrassed by her younger brother David. He is autistic and does things unlike Catherine wants him to. So Catherine creates a list of very specific rules for David about how he should act, what he should say, and things he needs to understand. She also develops a friendship with a paralyzed boy, Jason, who turns out to think like a regular person despite how he looks. He wants to do normal things, but he can't. Catherine tries to help him as best as she can, and she learns that its not always about what's on the outside, but on the inside.
