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.
Following three consecutive championship wins at the a cappella U.S. nationals, the Barden University Bellas are at the top of their game. Led by Beca Mitchell (Anna Kendrick), now in her senior year, and Chloe Beale (Brittany Snow), now in her fourth senior year, the Bellas put their lives on hold to travel across the country on a victory tour, with a stop at the Kennedy Center, where the group performs for President Barack Obama along with a crowd of influential a cappella lovers.
However, when an unfortunate wardrobe malfunction turns the beloved Bellas into a national disgrace (and viral video) the team is stripped of their eligibility to compete, banned from auditioning new members at Barden, and their remaining U.S. tour stops are given to a rival singing team from Germany: Das Sound Machine. Faced with harmonic dissonance and an uncertain future after graduation, the Bellas are given one final chance at redemption: set aside their differences and win at the global a cappella championship – where Das Sound Machine is heavily favored to take home the top prize.
