An intergalactic traveller from the planet called Bookala lands in Angel Grove Park. His tiny spaceship is powered by a special diamond, which, if Lord Zedd can steal it, can be used to power the always-drained Serpentera permanently! The Power Rangers get to the Bookala first, and attempt to aid him in returning to his home planet. Can they help him get off Earth without Zedd noticing, while dealing with both the Weldo and Evil Bookala monsters?
