Based on the long-running Power Rangers franchise, five teens from Angel Grove High are granted superpowers and giant robot dinosaur Zords to defend Earth against the alien villain Rita Repulsa.
The world is on lockdown. The Dinozords, now under the Black Dragon's control, are stationed around the globe invoking Rita's word as law. With the Rangers left powerless, Rita calls upon Tommy to make the ultimate sacrifice or risk Angel Grove's survival.
