Rita Repulsa is preparing her most ambitious attack yet, and this time she is bringing the fight directly to Angel Grove. Her palace comes down from the Moon as she prepares to unleash a massive assault against the city. The Rangers have faced plenty of monsters, but this threat is different because Rita is no longer content to attack them one monster at a time. With the entire city in danger, the Power Rangers must prepare for a battle that could determine whether Angel Grove remains safe or falls under Rita’s control.
