The Unbreakable Five: Bree, Flynn, Arielle, Claude, and Archer, are ready to begin the new school year after returning from the Eiffel Tower Music Festival Summer Camp Program in Paris. Every two years, Seaside Heights High School competes against its rival school, Sunshine City High School, in the Night Tournaments, and The Five are looking forward to them, especially since two new students have joined their grade. But when the tournaments begin, everything at Seaside Heights starts to go awry, and when it becomes too fishy, it's up to The Unbreakable Five, once again, to get to the bottom of exactly why Seaside Heights hasn't been winning the Night Tournaments for the last few years.
