Jenny, Lt. Stone's niece, comes to town with a chip on her shoulder, shunning an offer of friendship from Kat. The two soon end up competing for a sole spot at London's Royal Dance Academy. The auditions get quite heated, when Elgar plants a detonator disguised as a cassette player at the dance hall. If that weren't bad enough, Wolfgang von Griller orchestrates control over all vehicles in Angel Grove to come to life and fly around attacking the Rangers! And the Bulk & Skull Chimps' most recent attempt to get attention to their plight, involving the Juice Bar's funds, puts a strain on the relationship between Jenny and her uncle.
