With their powers and Zords gone, our heroes return to the Command Center, finding Alpha 5 & Zordon alive, but the whole place is wrecked. In an effort to figure out how to get new powers, Zordon & Alpha inform the six humans of the legend of Ninjor, keeper of the Lost Temple.
It seems that Ninjor forged the original Power Coins, and using a map found with the original coins, our heroes set out to find him. Meanwhile, on the moon, Lord Zedd, Rita, Rito and the other Evil Space Aliens celebrate their victory. Rito's eggs begin to hatch (all but one), turning out to be a new army of footsoliders: purple birds called Tenga Warriors.
Soon, the Rangers, following the map through the deadly Desert of Despair, encounter not only natural traps, but run into the Tengas. They DO find the Lost Temple, but the Tengas do also, planting Rito's final egg, that of a Vampirus monster, at the base of the place. Back on Earth, Bulk & Skull struggle to force themselves into making good on their word, and head for the Angel Grove Police Academy registration office.
