The broad narrative follows the misadventures of the last surviving human Arthur Dent, following the demolition of the planet Earth by a Vogon constructor fleet to make way for a hyperspace bypass. Dent is rescued from Earth's destruction by Ford Prefect, a human–like alien writer for the fictional, eccentric, electronic travel guide, The Hitchhiker's Guide to the Galaxy, by hitchhiking onto a passing spacecraft.
