Produced by the Italian director Alfonso Brescia, the film starts in the year 2312 on planet Earth, which is referred as "Sol 3" by the aliens. In an auction, the planet is sold to an evil tyrant named Kess, who flies to "Sol 3" and begins gathering android slaves to sell them other evil alien species. Rescuing the planet against its new owner are the kindly Professor Mauri and his band of human and robot friends. The team includes Irene (Yanti Somer), Dirk Laramie (Gianni Garko), Bridget (Malisa Longo), Shawn (Chris Avram), Norman (Roberto Dell'acqua) and two robots Tilt and Tili. The defenders set out to reclaim their planet from Kress and his cyborg army. To win against the alien race, who are 1800 years ahead in technology, victory seems impossible for the humans.
