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.
In order to regain their status after a humiliating event in front of the President, the Bellas enter to win the World Championship against the top a cappella groups. However, since NO American team has ever won before, the Bellas stand up for the challenge.
Three years after winning the previous competition, the Barden Bellas are now led by senior Beca Mitchell (Anna Kendrick) and three-time super senior Chloe Beale (Brittany Snow). The Bellas have become ICCA champions each of these three years. However, the group becomes involved in a national scandal, dubbed Muffgate, when Fat Amy Hobart (Rebel Wilson) accidentally rips her pants in front of U.S. President Obama during a performance on his birthday at the Kennedy Center, showing her genitals to the public since she did not wear underwear, leading to the Bellas' suspension from the ICCAs. Beca makes a deal to allow the Bellas to be reinstated should they win the World Championship of a Capella..
