Five Friends. One School. Big Problems. A new girl has just transferred into the GF5's class at Earhart Elementary along with her little brother. Fiona is quiet and thin and a bit forgetful as she didn't bring her lunch or snack to school. Lucy, Marina, Zara, A.J., and Sofia, The Geeky F@b 5, befriend Fiona, who is particularly impressed with Sophia's tablet, Marina's knowledge of space, and Lucy's fluffy kitty, Hubble. When Fiona gets called away to the principal's office after school, the GF5 don't know why. When walking home they discover she lives in a nearby motel, not a home. As they begin to understand Fiona's story, the girls learn that she and other kids like her are homeless and don't always have food. To help, the GF5 launch a citywide student food drive among grade schools. That explodes into a fierce competition to see which school collects the most food by weight. The winning school gets a big bash with a DJ. Which school will win? Even Hubble, the snarky cat, must contend with crosstown rival, the Madison Mackerel mascot, who hatches a diabolical plan to sabotage Earhart. Join the fun as GF5 rallies students to fight for Fiona.
