Molly, Simon, and Rosie are totally determined to win big and build the greatest science fair project in the entire history of their school. To make their brilliant vision come to life, the three best friends need to attract a massive swarm of beautiful, glowing fireflies right into Molly's backyard. The ambitious trio from Table 5 gets straight to work, hatching a clever plan to lure the tiny glowing bugs to their homemade trap. Unfortunately, their grand scientific experiment works a little too well. Instead of catching just a few fireflies, they end up shaking up the whole neighborhood and causing a brightly lit, buzzing disaster. Now, the friends are rushing against the clock to fix their glowing mistake before the big science fair officially begins. They will have to use teamwork, quick thinking, and a lot of humor to get the situation under control. Will their bright idea earn them a glowing grade, or will their big project flicker out completely?
