The unhappy inhabitants of planet Krikkit are sick of looking at the night sky above their heads - so they plan to destroy it. The universe, that is. Now only five individuals stand between the killer robots of Krikkit and their goals of annihilation. They are Arthur Dent, a mild mannered space and time traveller, who tries to learn how to fly by throwing himself at the ground and missing; Ford Prefect, his best friend who decides to go insane to see if he likes it; Slartibartfast, the indomitable vice president of the campaign for Real Time, who travels in a ship powered by irrational behaviour; Zaphod Beeblebrox, the two-headed, three-armed ex-head honcho of the universe; and Trillian, the sexy space cadet who is torn between a persistent Thunder God and a very depressed Beeblebrox.
