An evil sorceress named Rita Repulsa escapes from her space dumpster prison and begins a quest to take over planet Earth. Fortunately for Earth, Zordon - a wise old sage trapped in a time warp, has prepared for just such an occasion. Using his constant companion, Alpha 5, Zordon recruits five teenagers from Angel Grove to take on Rita and her henchman - Squatt, Baboo, Finster and Goldar. The five teens, Jason, Kimberly, Zach, Trini and Billy, each have special skills and strengths that make them "Morph" or change into a group of nearly indestructible super heroes called "Power Rangers." Rita, determined to succeed in her quests sends down Goldar and her Putty Patrol to battle the novice Rangers. But, the teens call on their Dinozords, large battle vehicles shaped like dinosaurs, to help them defeat the Putties and cause Goldar to retreat to the moon.
Trini must overcome her fear of heights to save Billy.
Kimberly and Trini gather enough signatures to close down a nearby polluting dumpsite. Unaware that the dumpsite is controlled by Rita, the girls go there and are attacked by Putties. Zordon summons the Rangers and he informs them of the danger the girls are in. The Rangers plan to come to the girls rescue, but Zordon makes them fight Rita's latest monster first. Zordon shows them the power of their new weapons and warns that they can only be used to defeat Rita's monster. The Power Rangers join together to form the Mighty Power Sword. One laser blast causes Rita's monster to be defeated. The Power Rangers learn that even big obstacles can be overcome with teamwork.
