A yacht explodes off of California’s beautiful Malachite Beach, where Nancy, Bess, and George have been vacationing. In order to save the now toxic shore, celebrity event planner Stacey Manning organizes a star-studded fundraiser at a beachfront mansion. The girls can’t believe they’re part of an A-list party headlined by singer Miss Zaza, gourmet chef André Walters, and reality TV stars the Casabian sisters.
Stacey asks the three friends to help with the party by moving into the mansion, but they hesitate: This place was headquarters for Roland’s Renewal Retreat, a mind-controlling cult that they barely escaped! One by one, the rich and famous followed by Nancy, Bess, and George, become targets of deadly foul play, and now that the girls have moved into the sinister mansion, they worry: Will they ever get out… with their lives?
