Zhane's Destiny

The Rangers pick up a signal which leads them to a planet under a constant sandstorm. They're unaware it's also current home to the former inhabitants of the colony of KO-35, Andros & Zhane's homeworld, who're staging a rebellion against Dark Specter's forces in secret. The four Earthen Rangers are captured by the rebels, and thanks to a traitor in their midst, are led to believe they're spies for Dark Specter, and the source of an infectious attack by the Coralizer monster.
