Gabby Espinoza (Adrienne Bailon) is captain of the Cathedral High Phantoms volleyball team.

Having to go to different schools and split up, the three Madonnas Lauren McDonald, Katilin, and Becca chose Cathedral High and joined the volleyball team.

Tension forms between Gabby's group Lettie and Rada and the Madonnas, causing them to lose during a volleyball game because of lack of teamwork.

After winning, Gabby and Lauren are back on good terms, agreeing that both should concentrate on their games first and deciding afterwards who should get the boy.

Gabby begins to lose focus, the coach suspects she's on drugs and orders her to sit on the bench, replacing her with Becca.
