Kimberly's sickness turns into a useful weapon when facing Repellator. The Rangers must help Masked Rider and the rebels put a stop to the Cogworts and Plauge Patrol, and in the process, strike a blow for freedom on Edenoi. Then, they'll have to get back to Earth in time to help their ill teammate face the Repellator monster! And, are Bulk & Skull in over their heads when the monster thinks they're actually Rangers?
