Let's see, it's been a while since I heard it! But basically there was this princess named Snow White, and she lived with seven dwarves. One day she was poisoned by an evil witch with a cursed apple, and only a kiss of True Love could wake her up. Conveniently, a handsome prince came by the cottage one day and did just that. They lived happily ever after.
Or at least that's how it goes in most children's versions. I hear the original and other kinds are a bit darker! I-it's a little silly sounding, huh?
