One night, a little boy is awoken by his cat, Sylvie. Everyone in the house is sleeping, but outside, the Night World is wide awake!

Beginning with a beautiful black-and-white palette, the shadows of the Night World come to life: lilies, sunflowers, rabbits, deer, and owls are all revealed as Sylvie and the boy explore the world outside his door. But the animals all know something new is coming--what could it be? Finally, in an explosion of color, the dawn arrives.
