A Nigma High is consumed by a Flu Epidemic, Lee included. Lee's cell phone containing the Prank Song is stolen by the Tazelwurm. Lee chases the Tazelwurm to an underground laboratory, where he learns the Prank Song was developed there. The Tazelwurm gives Lee a folder containing all the information about the Prank. Unfortunately Lee is captured by the Cleaners, is knocked unconscious, and dragged back to detention where he wakes up and writes the experience off as a bad dream. In a Sub plot Holger, Camilio, Brandy, and Chaz are attempting to escape the school before the flu turn them into "Zombies" too, and Principal Barrage does battle with his old enemy "Colonel Von Virus".
