An angelic representative of the race that spawned the demonic Count Iblis (the villain in the two-part War of the Gods) anoints Apollo (Richard Hatch) as the potential savior of Mankind. Sent to Terra in the guise of a long-lost astronaut, Apollo must prevent a nuclear holocaust at the hands of the dreaded Eastern Alliance. "Experiment in Terra" was later combined with "The Return of Starbuck", an episode of the Battlestar Galactica spinoff Galactica 1980, and reissued as a two-hour "TV movie", also titled Experiment in Terra.
