Alien sorceress Rita Repulsa and her army of monsters emerge from space to conquer Earth. All that stands in their way are five teenagers with attitude who draw on dinosaur powers to transform into the Mighty Morphin Power Rangers.
With the Angel Grove High talent show around the corner, the Rangers have a lot to deal with when Tommy is kidnapped and imprisoned by putties, and Finster creates the Fang monster in celebration of Rita's birthday.
The Ranger teens form a Clean-Up Club and take part in cleaning up Angel Grove Park, but Rita has plans of her own and sends the Polluticorn monster after them.
