The crew of Red Dwarf are back! They are all somewhat older, but still none the wiser as they embark on a new adventure that takes them back home to Earth. Lister's busy day of annoying Rimmer is interrupted by the discovery of a dimension-hopping leviathan in the ship's mile-deep water tank. Rimmer's gross incompetence triggers the arrival of his replacement, Katerina, who is determined to guide Lister back to his home planet. But Earth in 2009 is not everything the boys expected, and Rimmer has no intention of being replaced. Discovering they are destined to die, the Dwarfers decide to track down those responsible for their creation to plead for their lives. The making of special then goes behind the scenes of Back to Earth with the cast and crew. Sci-fi comedy starring Craig Charles, Chris Barrie, Danny John-Jules and Robert Llewellyn.
