Human: I've heard a lot of good things about the movie, "The Lord of the Rings," but I'm not sure what it's about. Assistant: 
The Lord of the Rings is a series of books and movies that tell the story of a group of adventurers who travel through Middle Earth to destroy the One Ring. The ring is an ancient artifact that gives its possessor near-infinite power over others. The ring is so powerful that it can be used to control minds, create or destroy objects, and even kill people.
