The Nightingales are in a serious funk. Bradley Academy's all-girl a cappella group used to be the pride and joy of the sunshine state, but the Nightingales have fallen out of harmony. Best friends and co-captains Lidia Sato and Sydney Marino aren't speaking. A boy has come between them — none other than Griffin Mancini, the obnoxious lead singer of Bradley's smug all-boy a capella group, the Kingfishers. The Nightingales have no chance at winning the big state final if their captains are at each other's throats. Their only hope is new girl Julianna Ramirez. She's super shy, but she has some serious pipes. The three girls — and the whole group — will have to come together if they want to beat the Kingfishers and their rivals from Julianna's old school.
