Avery has just moved to southern California with her mom after her parents' divorce. She dreams of swimming with dolphins, but a near-drowning incident years ago has left her fearful of the ocean. Maria longs for space and quiet among her big, loud family. She dreams of acceptance to a prestigious art program for her drawings of dolphins, but knows her parents think art is impractical. Then a unique-looking dolphin leads the two girls to meet in a secluded cove. As Avery and Maria observe the dolphin and become friends, they push each other to overcome their fears. But their opposing backgrounds and personalities lead to a disagreement that threatens to tear their friendship apart. When it seems their special dolphin is in trouble, can they overcome their differences and help the dolphin - and each other - before it's too late?
