When detectives Sikes and Francisco are presented with the mysterious death of an Eeno, Matt is stupefied to discover that George rudely snubs the case. He, like most newcomers, reviles the outcast Eenos. As the case unfolds, George has to reassess his prejudices, and George's family help save the city from an alien threat originating in an Eeno waste disposal facility.
Unfortunately the movie Alien Nation: The Enemy Within is not yet available on HBO Max.
