The story of The Hitch Hiker's Guide to the Galaxy begins when a 6-foot ape descendant named Arthur Dent is saved from the destruction of planet Earth thanks to Ford Prefect, who is in fact from a small planet somewhere in the vicinity of Betlegeuse, and not from Guildford as Arthur had first thought.
