Timmy Turner (Tara Strong) and Jimmy Neutron (Debi Derryberry) are preparing for their upcoming Friday the 13th school dances. Remembering his time with Cindy Vortex (Carolyn Lawrence) from Retroville, Timmy decides to pick her up and take her to Dimmsdale, creating another rivalry between Jimmy and Timmy, of which Professor Calamitous (Tim Curry) thinks he can take advantage. However, not even Neutron's archnemesis is safe when Anti-Cosmo (Daran Norris) breaks Anti-Wanda (Susanne Blakeslee) and all of the other Anti-Fairies out of Fairy World Prison to bring a lot of bad luck to Timmy's universe, that Friday the 13th could remain on the calendar forever.
