Fortune is on our heroes' side at the beginning of Episode 6 as the transporter on the ship is still working. However, Marvin has to sacrifice himself in order that the rest can be transported. The four get separated and Arthur Dent and Ford Prefect find themselves on a Golgafrinchan ship that is programmed to crash land on a planet not unfamiliar to the pair of them. The series concludes with them stuck on a prehistoric Earth along with the Golgafrinchans - and the dwindling population of natives.
