The team reopens the 1997 death of then 16-year-old cheerleader Rainey Karlsen, who died from drug overdose, believed accidental, but now an anonymous confession to her murder, with an atom sketch, is found in a modern art exhibit along with new suspicious evidence. She joined the cheer-leading squad with her spineless buddy Celeste Church, but unlike her refused to dance to the tunes of tyrannical airhead queen bee Becca Abrams, and even confronted popular teacher and coach Pruit, whom she might even 'expose as a pervert' for allowing hazing and other dubious traditions. The note came from Joe Vives-Alvarez, who supplied the drugs, but the fatal night was the girls' own bitch-doing.
