The wayward traveler -- Lemuel Gulliver -- ends up on a series of bizarrely populated islands. First he is a giant among little people, but then sees the situation reversed when he's surrounded by giants twelve times his size. Next he finds himself in the clouds, in a society of devoted but ultimately hapless mathematicians. Lastly, his journey brings him to an island where incredibly noble horses must deal with a race of uncouth, reviled ape-men: the Yahoos.
