A big moment in a little boy's life... It's the night before Tom's first day at school and he can't sleep, but magic is in the air... Tom finds himself shrinking to the same size as his toy mouse, Small, and a fantastic night-time adventure begins. The two friends fly in a model plane, high above Tom's new school. When he peeks through the school window, Tom is delighted to see his name on a sticker above a coat peg, and feels reassured and confident to face his big day tomorrow.
