The Rangers kids are at last able to help those who've helped them, as they manage to revive the water-depleted Aquitians. But even if Billy can restore the world's water supply, can the Alien Rangers put an end to Hydro Hog before he drains it again? Elsewhere, in Africa, Young Aisha locates the last Zeo sub-crystal at her new friend Tanya's tribe. She's faced with an important decision between completing her mission or helping find a solution to the animal-effecting famine. Thanks to the surprising success of Rito and Goldar, even if the Rangers can restore the Earth to its proper time, our heroes' lives will never be the same!
