When Mandy discovers that a mysterious source has created a social network called Mandybook in her honor, she's thrilled, especially when she gets over 100,000 followers within the first hour! But things quickly go downhill when her followers literally start to follow her, and not in a good way. What Sam, Clover, and Alex eventually uncover, after Jerry sends them on a mission to investigate a strange, mind-controlling frequency emanating from somewhere near their campus, is that the network's creator, Telly Hardwire, is to blame. In an effort to get revenge on Mandy for not wanting to be his cyber-friend back in high school, he has engineered Mandybook to be a recruitment tool to create an army to take her out! In a B-story, Clover is upset when her Fashion Design teacher, Professor Plunkett, is impressed with Sam and Alex's designs but not hers.
