Before there were humans, a handsome young hare named Fine Ears was sitting on the prairie gazing at two moons: Big Sister and Little Sister. He is joined by a very large white hare named Big, who is adept at predicting the future. Big explains why there are two moons but someday there will only be one. He also warns Fine Ears to be wary of the two-legged creatures who will someday come to the prairie.
