entire graduating class, including Sam, Clover and Alex, mysteriously blacks out! When they wake up back at school, they’re not sure what happened. Was graduation just a dream? And weirder still… BH seems to have undergone some “changes” in their abs... (more)ence. The students soon realize this isn’t Beverly High at all – it’s actually a replica of the school… where they’re being held captive (thanks to a high-tech security system that keeps them imprisoned)!!! Sam, Clover and Alex eventually discover that Chet is to blame. His plan? To force everyone to stay in high school forever, reliving their “glory days” over and over and over again (a thought that horrifies the Spies – after all, they’ve spent enough time with Mandy already)! And anyone who resists will be forced to work as servants (slinging hash in the caf, cleaning the restrooms, and doing other menial tasks that keep the faux-school running). Will the girls be able to save their classmates just in time to graduate?! In a b-story, the girls deal with the sad reality that, after graduation, they may be going their separate ways.
