Frax schemes behind Ransik's back to create a powerful fuel source common in the future, but not yet invented. To do so, he has a mutant loot Bio-Lab, Mr. Collins' multi-faceted company. But Wes' father doesn't take the criminals' constant attack of the city lying down, and has a former research vehicle turned into a massive drill-tank known as Raimei! Meanwhile, the Rangers' Megazord is heavily damaged in battle, and they'll have to wait while they're repaired in the future. But when Frax's Tri-Zirium-powered Tronicon robot attacks the city, can they just stand by and let Silver Hills be destroyed? Or will the Raimei tank save the day? And just what is that Mystery Man in the year 3000 testing, and how will it help our heroes?
