Frank and Joe track down pranksters trying to make a sixteenth birthday much less sweet.
Rich girl Lindsay Petyon is throwing the biggest and best Sweet Sixteen bash that Bayport has ever seen. But her party planning is off to a bad start when Frank and Joe discover that someone has keyed her very expensive car – an early birthday present – and has put the mean prank up on YouView.
Soon after the prank goes viral, a group calling themselves the Scaredevils begin to film themselves committing acts of violent vandalism around town. Broken windows, dumpster fires, and more threaten the security of Lindsay’s party – and of Lindsay herself.
Frank and Joe are determined to figure out who is the mastermind behind the videos before Lindsay’s Sweet Sixteen turns into a party she will never forget… for all the wrong reasons.
