The series depicted Logan and Jessica -- pursued by Francis (Randolph Powell) -- traveling in a futuristic hovercraft-like vehicle on a cross-country trek to Sanctuary in a post-apocalyptic America. The domed city was seen only in the pilot and two other episodes, using recycled footage from the film. In a change from the book and film, the television series had the city run by a cabal of elderly citizens; Francis has been promised a life beyond thirty as a city elder if he can bring back the fugitives. Logan and Jessica were joined on their journey by an android named REM, played by Donald Moffat.
