As Newcomers - fugitive slaves from the planet Tencton - Detective George Francisco and his family face prejudice and intolerance as they struggle to assimilate to life on their adopted planet. Together with his human partner, hard-edged Detective Matt Sikes, George walks the beat in Slagtown, Los Angeles, a Newcomer slum teeming with vice and corruption. More than just another cop show science fiction show, "Alien Nation" utilises a unique and exciting blend of action, suspense, humour, and social drama to explore the sociology of what it means to be an outsider striving to fit in.
