A peaceful summer day is rudely interrupted by the sudden return of the evil villains Widow and Roki Repulsa. They've come home from their trip stronger than ever before. Leaving the Rangers a present of new and improved Dark Putties, the Rangers, despite a summer of preparation for this day, find themselves ill prepared to against this threat.

With their team fully assembled, the Power Rangers still can't rest. Zita makes a reappearance, crashing with Grandpa at Tai's house, and gives Tai a mysterious object as a sort of peace offering. Widow has another devious plan for the Rangers, and this time the Megazord is in her cross hairs. Making a personal appearance to confront Taran and the Legends to ensure they can't interfere, she takes a direct hit of his white magic. While pregnant! How will the Rangers get by with only Megazord when another monster attacks. Will the gift from Zita hold the answer. And what will Fox do when he returns from the jungle to learn that he's no longer a Power Ranger?

Tai gets ready for Rex to return and enlists the help of Nathan and Mason to help him pack and move Rex's wardrobe to his off-campus apartment. But things are stirring in outer space. Griff and Lammy sense something coming. Something from their past. Taran and Widow both sense it as well. As Widow sends a monster to Earth to combat the Power Rangers, Rex and Zhane's shuttle falls under attack from a mysterious enemy, but an enemy Griff and Lammy give a name to. Dr. Lee Keflen. What twists, turns, and surprises are in store for not only the Power Rangers, but the Palace on the Moon? Can they handle what's coming next?

The Rangers and everyone else is in for a shock when a woman claiming to be Astronema appears. The Rangers learn that she's a clone of Karone, engineered by a mad-man called Dr. Lee. Titus, a clone of Lammy and Widow, makes an appearance as her bodyguard along woth a woman called Nubia. Astronema sends them to Earth to further Dr. Lee's plans. While there Titus runs across Zita. Is his predicament enough to capture the interest of a space witch at a crossroads? Can the Rangers handle a dangerous new type of monster?

Things are getting tight for the Power Rangers. With one of their Megazords down and new villains to deal with, they really feel the pinch. Widow and Roki send a monster that turns friends into enemies, but Astronema activates one of Dr. Lee's Chimera at the same time. Can the Rangers contend with rivals within their own ranks and without in order to defeat the dual threats facing them and prevail?

Widow and Roki are up to no good, but what exactly is behind the monster they send to Earth. Capturing in playing cards people in pink, what is the true goal of the Queen of Hearts, Rosie O'Hare?
