Three years prior to the series' beginning, an AI computer virus called Venjix took over all of the Earth's computers, rendering all communication useless while creating an army of robot droids to destroy everything. Humanity's last safehaven became the domed city of Corinth. Surrounded by Venjix's forces and a force field, it is nearly impossible to enter without luck or firepower. When the force field is lowered to allow surviving humans sanctuary, Dr. K's RPM Power Rangers fight Venjix's forces to protect Corinth from being destroyed.
