Alien Nation: The Enemy Within (original airdate: November 12, 1996) was the fourth television film produced to continue the story after the cancellation of Alien Nation. It was written by Diane Frolov and Andrew Schneider, and directed by Kenneth Johnson.

Plot

Detective Matthew Sikes and his Tenctonese partner George Francisco investigate a group of Tenctonese called the Eenos. The subplot involves Tenctonese binnaum Albert Einstein and his new bride May attempting to have a child (with George's help) -- a reversal of the Alien Nation episode "Three to Tango".

Production

Shot back to back with Alien Nation: The Udara Legacy as part of a ten-week shoot termed “grueling,” actors were under the impression these movies were the end of the series.
