Divatox brings her Subcraft and her evil crew of monsters back to Earth, intent on making the Power Rangers pay for ruining her wedding plans with Maligore by ruining their lives. It just so happens that Adam, Tanya, and Kat are graduating from Angel Grove High today (Tommy got his diploma early and is helping his uncle on his stock car racing crew), and use the time to bring fellow graduate and former Ranger Rocky (and the viewers who missed the Turbo Movie) up to speed on their adventure on Muranthius. In an effort to spoil their graduation, Divatox sends Elgar to the Angel Grove Power Plant with a detonator, where he encounters Bulk & Skull, and proceeds to monkey around with their genetic structures! With his teammates busy with the most important day of their teenaged lives, Justin is alone as the Blue Turbo Ranger to defend the plant! (thetvdb.com)
