Pitch Perfect 2

In 2015, The Barden Bellas have been the ICCA National champions for three consecutive years and are now led by senior Beca Mitchell and three-time super senior Chloe Beale. A national scandal (dubbed "Muffgate") erupts when Patricia "Fat Amy" Hobart accidentally rips her pants in front of U.S. President Barack Obama during his birthday performance at the Kennedy Center, exposing her genitalia and leading to the Bellas' suspension from the ICCAs despite Beca saying that it was all an accident. Beca makes a deal that they can be reinstated should they win the A Cappella World Championship. Freshman Emily Junk hopes to follow in the footsteps of her mother, Katherine, by becoming a Bella. She watches an a cappella performance by the Treblemakers, now led by Beca's boyfriend Jesse Swanson. Jesse's friend Benjamin "Benji" Applebaum, develops a crush on Emily. The Bellas learn that German powerhouse group Das Sound Machine (DSM) has replaced them on their victory tour and is favorite to win the Worlds. Beca has secretly started an internship at recording studio Residual Heat, which only Jesse knows (and Fat Amy later discovers). As the Bellas' suspension means they cannot hold auditions, Emily goes directly to their sorority house and sings her unfinished song "Flashlight". They decide she can join; since she came of her own accord, they technically aren't breaking any rules. The Bellas meet DSM when the latter performs at a car show. DSM leaders Pieter Krämer and Kommissar mock the Bellas. Both groups are invited to a riff-off with the Treblemakers, the Tone Hangers (composed of former Treblemakers, including previous leader Bumper Allen, with whom Amy is in a casual relationship), and the Green Bay Packers. The Bellas make it to the final two, but lose to DSM when Emily sings "Flashlight", violating the rule of no original songs. Bumper asks Amy on a traditional date and to officially be his girlfriend; she refuses. At a practice performance for the Worlds, the Bellas' set ends in disaster when their pyrotechnics set fire to Cynthia Rose's hair. Chloe takes The Bellas on a retreat to rediscover their roots and synchronicity, led by former Bella Aubrey Posen. Beca's internship is revealed, and Beca argues with Chloe over her obsession with the group and accuses the other Bellas of not thinking about their futures. She storms off, only to step into one of the camp's bear traps. Beca apologizes before being saved by Lilly. The Bellas accept that they will go their separate ways after graduation, and regain harmony by singing "Cups", Beca's audition song for the group. Amy regrets ending things with Bumper and they reconcile. Beca's boss has been unimpressed with her, so Beca offers to help Emily produce "Flashlight". He likes the result and says he looks forward to working with them. The senior Bellas graduate and the group heads to Copenhagen for the World Finals. Emily and Benji share a kiss. The Bellas deliver a stripped-down performance ending in a harmonized version of "Flashlight" with Aubrey, Katherine, and other past Bellas joining in. They win. As the senior Bellas leave Barden, they give Emily a belated initiation ceremony, with Amy demonstrating the last tradition: christening the house by sliding down the staircase.
