Earthman Arthur Dent is having a very bad day. His house is about to be bulldozed, he discovers that his best friend is an alien--and to top things off, Planet Earth is about to be demolished to make way for a hyperspace bypass. Arthur's only chance for survival: hitch a ride on a passing spacecraft. For the novice space traveler, the greatest adventure in the universe begins when the world ends. Arthur sets out on a journey in which he finds that nothing is as it seems: he learns that a towel is just the most useful thing in the universe, finds the meaning of life, and discovers that everything he needs to know can be found in one book: The Hitchhiker's Guide to the Galaxy.
