It follows the television series format of two parallel storylines. The first plot is about a seemingly human-Tenctonese hybrid child involved in a sinister experiment with a Newcomer scientist disguised as a human. The sub-plot is the budding relationship between Matt Sikes and his Tenctonese neighbor Dr. Cathy Frankel. The relationship between Matt and Cathy was an ongoing theme of the Alien Nation television series.
In a recapitulation of the series cliffhanger, Alien Nation: Dark Horizon begins with Susan Francisco and her daughter Emily falling victim to a newly developed bacterial infection that was created by a group of human Purists to exterminate the Newcomer species. There is also a new sub-plot running parallel to this one, the story of Ahpossno, a Tenctonese Overseer who lands on Earth to find any surviving Tenctonese and bring them back into slavery. The idea of a signal sent into space by the surviving Overseers was explored in the Alien Nation episode Contact.
The plot follows human detective Matthew Sikes and his Tenctonese partner George Francisco as they investigate a mind-altering Tenctonese artifact being used to lure followers into a deadly cult. The artifact used in this movie was the same one from Alien Nation episode Generation to Generation.
In this movie, detective Matthew Sikes and his Tenctonese partner George Francisco investigate a group of Tenctonese called the Eenos.
