Lord Zedd has to take his centeniall slumber, where he naps for a few weeks once every hundred years. Given this time off, the Ranger Teens, along with Bulk & Skull, go on a school-based vacation in Australia. Little does ANY of them realize, that Rita Repulsa has managed to steer her Space Dumpster back to the moon. She crash lands, sneaks into the Lunar Palace, meets up with her still-loyal servant Finster, and gets restored to her normal height. Rita uses Finster's love potion on Zedd while he sleeps. By the time he wakes up, she's been given a make-over to make her face younger ("I don't look a day over 1000!", she claims).
Lord Zedd instantly falls in love with her, as expected. He plans a major wedding, which is exactly what she'd hope would happen, wanting to share his power, then eventually betray him when he least expects it. On Earth, Alpha leaves the Command Center for a relaxing stroll. Finster teleports down, and inserts a virus into his system!
Alpha goes haywire, acting cruel and evil. He silences Zordon, and tricks the Rangers, still Down Under, to go to an abandoned theater. They do as ordered, but upon teleporting in, they discover that not only can they not teleport out, but the theater's filled with an army of previously destroyed monsters!
