Musician Ricky Mathis becomes an overnight sensation thanks to his song "Rock Legend." When his music causes his fans to become obsessive and destructive, Sam, Alex, and Clover are called in to investigate the cause of this fanatical behavior under the guise of a supporting band. While Clover is enchanted by Ricky's music, Sam and Alex investigate the recording studio and discover they are using special glowing CDs that brainwash listeners. They must stop manager Sebastian Saga from using Ricky's music to take over the world. In the subplot, Clover has a crush on schoolmate Damon Reynolds, who plays guitar and hangs out with school diva and rival Mandy.

The girls travel to the African Nation of Lyrobia to investigate a strange kidnapping attempt against that country’s Queen Tassara -- a kidnapping attempt with an anti-gravity ray! After Clover, who’s disguised as the Queen in order to protect her, is abducted from the palace, the girls and the real Tassara must go after her. They eventually discover that Makeda, the Queen’s jealous sister, is the kidnapper -- and she wants to keep her sister from signing a peace treaty with neighboring Kenyopia so that a twenty-year war between the two countries will continue and she (due to a deal she made with the General of Kenyopia) will become Queen. Can the girls stop Makeda and get Tassara to a peace summit in Geneva before it’s too late? In the b-story, Clover and Mandy compete for the title of Homecoming Queen.

The girls arrive at WOOHP to find that Jerry has retired. In his place is Mac Smit -- a handsome, charismatic, intelligent, cool, thirty-something who Sam develops a bit of a crush on. When strange things start to happen (the credit card Mac gave them turns evil, the car he lent them explodes) the girls deduce that someone is after Mac. As they follow clues to find out who the unseen assailant is, the girls soon discover it is Mac himself (he’s really a rogue WOOHP agent named Tim Scam). Mac’s plan is to use an Evapo-Blaster -- a device he developed when he was at WOOHP -- to dehydrate all the earth’s water. But first he must get rid of the spies -- just like he’s gotten rid of Jerry! In the b-story, the girls grow sick of the way Jerry is treating them and wish they had a new guardian.

The brains of the world's top scientists are being sucked dry by strange creatures from the ocean controlled by a former janitor who wants the world's memories in his hands! In the sub-plot, Sam saves Mandy and her hair after releasing it from a clay pot! Mandy wants to be Sam's best friend but actually cramps her style in the process!

Research Lab Scientists are being kidnapped into the middle-ages. In a B- story, Clover really wants to win the Halloween Contest that Mandy and her are competing over.
