Alien Nation Alien Nation is a science fiction television series, loosely based on the movie of the same name. Gary Graham starred as Detective Matthew Sikes, a Los Angeles police officer reluctantly working with "Newcomer" alien George Francisco (from the planet Tencton), played by Eric Pierpoint. Sykes also has an on again-off again flirtation with a female Newcomer, Cathy Frankel, played by Terri Treas.
A flying saucer crashed in the Mojave Desert and its inhabitants turned out to be alien slaves, bred to be super intelligent and strong, and controllable by their Overseers. These Tenctonese, or "Newcomers", have been assimilated (sort of) into the population of Los Angeles.
