Arthur Dentil (Martin Freeman) on väga halb päev: tema maja on määratud lammutamisele, ta saab teada, et ta parim sõber on tulnukas ning selgub, et planeet Maa hävitatakse, kuna see jääb ette tulevasele kosmilisele kiirteele. Arthur asub teekonnale, mille käigus selgub elu mõte, et asjad pole nii nagu paistavad, ja et kõik, mida tal on vaja teada, seisab kirjas ühes raamatus: "Pöidlaküüdi reisijuht galaktikas"
Don't Panic! The story of Arthur Dent, an average Englishman who life was spared by his friend, who turned out to be an alien, while the planet Earth is destroyed.
