The Vacsacker monster sweeps through Angel Grove, sucking up citizens (including Bulk, Skull, Professor Phenomenus, Carlos, Andros, and Carlos' pal Silvy) and ejecting them in the domed Secret City, all part of a plan by Astronema to turn them into own evil soldiers. It's up to Ashley, TJ, and Cassie to infiltrate the city in an attempt to break the dome, to allow themselves and their captive teammates to be able to Morph to save the prisoners. When Andros confronts Vacsacker with only his Battlizer to power up his bare fists, will Silvy's incessive curiosity unleash a a previously unknown secret weapon of the Red Ranger, or will it spell the end for everyone?
