Résumé: Arriving at her new college, Beca (Anna Kendrick) finds herself not right for any clique but somehow is muscled into one that she never would have picked on her own: alongside mean girls, sweet girls and weird girls whose only thing in common is how good they sound when they sing together. When Beca leads this a cappella singing group out of their traditional arrangements and perfect harmonies into all-new mash-ups, they fight to climb their way to the top of college music competitions.
