National Velvet (1945) on Netflix

In the English coastal village of Sewels in Sussex, 12-year-old Velvet Brown and her older sisters, Edwina and Malvolia, happily finish their last day of school before summer vacation. While walking home, Velvet meets young drifter Mi Taylor and strikes up a conversation with him. As the horse-crazy girl is talking to Mi, she sees a beautiful, rambunctious gelding being chased by its owner, farmer Ede, and is awestruck. When Ede then questions Mi about his business in Sewels in Sussex, Velvet, who is impressed by Mi's knowledge of horses, insists that he has been invited to dine with her family.
