Plot summary

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..
