Filled with incredible computer generated animation, "Legacy" is a short but sweet look at a new species who has come much too late to a blue planet to learn about what makes us tick. In it, a nameless humanoid alien is assigned to abduct and study the species known as "human," but when it arrives on our planet in its gargantuan ship, it is shocked to discover that the planet has become nothing more than a deserted crater void of any known life, save for a doll's head and parts of a mannequin.
