The Rangers are training in the SimuDeck, when a bolt of lightning strikes the Astro Megaship, turning the holographic-simulation drones, the Craterites, into living creatures! They pile out of the Megaship by the dozens, and infiltrate Angel Grove, capturing adults and disguises themselves in their place. A young boy named Patrick, known for crying wolf and telling huge lies, discovers this evil plan, but will anyone believe him? Bulk, Skull, and Prof. Phenomenus, while trying to evesdrop on any discussions in town about aliens, witness the Craterites landing. Can the bumbling trio alone save the city?
