College student Beca knows she does not want to be part of a clique, but that's exactly where she finds herself after arriving at her new school. Thrust in among mean gals, nice gals and just plain weird gals, Beca finds that the only thing they have in common is how well they sing together. She takes the women of the group out of their comfort zone of traditional arrangements and into a world of amazing harmonic combinations in a fight to the top of college music competitions.

The Bellas are back, and they are better than ever. After being humiliated in front of none other than the President of the United States of America, the Bellas are taken out of the Aca-Circuit. In order to clear their name, and regain their status, the Bellas take on a seemingly impossible task: winning an international competition no American team has ever won. In order to accomplish this monumental task, they need to strengthen the bonds of friendship and sisterhood and blow away the competition with their amazing aca-magic! With all new friends and old rivals tagging along for the trip, the Bellas can hopefully accomplish their dreams.
