Jack Powell is about to tackle his biggest adventure ever... the fifth grade!
- Science Fiction
Jack Powell suffers from an affliction that makes him grow four times faster than normal, so the 10-year-old looks like a 40-year-old man. After years of being tutored at home, Jack convinces his overprotective parents to send him to public school. The children don't know what to make of Jack, but with the help of his fifth-grade teacher, he makes an effort to win them over.
