Mesogog, now split from Mercer, readies his transmogrifacation beam, which will turn all of humanity into dinosaurs. To power it, he'll need the Dino Gems. But to start with, he siphons off Elsa's lifeforce. Instead of being destroyed by it, she's somehow teleported to Zeltrax, and reverted to a near-amnesiac civilian form. The Rangers face Zeltrax again, and free his captive, stunned to learn who she is, just as much as she is to learn it as well! Trent makes a deal with Mesogog to trade the Dino Gems for his father. In doing so, he allows his teammates to sneak onto the island fortress and with the help of Hayley's latest invention, blast the dinosaur-izer beam before it can be fired! Trent barely makes it out in time as Mesogog's lab explodes around him, rescuing not only the Gems, but Anton Mercer as well. Little do they know, that while they were gone, Zeltrax infiltrated Tommy's secret lab, recaptured Elsa, and destroyed the place! Also, Devin works up the courage to ask Cassidy to the prom. But the matter of finding the Rangers' secret identities or face being fired from their News Reporting job gets in the way. Luckily, he happens to stumble upon the DT team morphing, and actually succeeds in filming it!
