The Rangers are powerless after the destruction of their Zords. To restore both, the six teens plan to seek out their source of creation. Zordon and Alpha 5 tell them of the legend of Ninjor, an ancient sage who forged the Power Coins long ago. Our heroes set out to cross the dangerous Desert of Despair in an effort to find the Lost Temple of Ninjor, who may not even exist! Meanwhile, Rito's first egg-presents hatch into a new group of treacherous footsoldiers for Rita & Lord Zedd: purple birds called Tenga Warriors! And also, Bulk & Skull face the perils of registering at the Angel Grove Police Academy.
