In this classic sci-fi advenure, the main characters from Galactic Mission, including The Empress Adriana, are working to divert comets away from earth by firing a missile from Mars. Adriana has decided to stay in human form, but seeks a closer relationship with James, who prefers Lara. He backs away. Adriana is restricted in power, although Captain Dryson and Alfredo - two android machines - carry out her instructions. After the comets are directed away from earth, Galactic Force returns with Antar-XP200, and two new androids, to replace Adriana, on Mars. Adriana regains full power and a chosen group leaves for earth by space ship with the intention of gaining control over Quadrant, who are returning, now that earth has been saved.
