Power Rangers R.P.M. plot
Venjix, an evil and rapidly evolving computer virus, has ravaged Earth with an army of Grinder droids and enslaved the remaining humans. Only the city of Corinth remains, protected by a nearly impenetrable force field from the poisonous atmosphere of the wasteland beyond. To fight Venjix's advancing evil, the mysterious Doctor K creates the "RPM Power Rangers" and recruits Scott, Flynn, Summer and Ziggy to operate the advanced weapons, vehicles and equipment. As a team, they try to stop the attacking machine army bent on world domination.
