Ray's family has just moved to a house surrounded by cornfields in the country. Ray has been kept home from school for the year as the family adjusts to their new locale. Spurned by his older brother and sister for being too young, and finding himself with long spells of solitude in a landscape full of unknown and imagined perils, Ray stumbles upon an old horse on a hilltop. He befriends the horse whose fenced pasture is like the tip of a green wave in the rolling sea of cornfields. But when the rainy season comes, and the horse is left exposed in the wind and rain, Ray reaches beyond his fear toward gallantry.
