After the highs of winning the World Championships, the Bellas find themselves split apart as they discover there aren't many job prospects for acapella singers. To keep the group together, they jump at the chance to reunite for an overseas USO tour, though they first have to face competition from other performers.
Something else also tests their loyalty – when Beca (Anna Kendrick) is singled out to sign with a record label. Will the Bellas be pleased for her success, or will it cause jealousy within the group?
Four teenagers — Spencer (Alex Wolff), Bethany (Madison Iseman), Martha (Morgan Turner) and Anthony a.k.a. "Fridge" (Ser'Darius Blain) — are given detention and told to clean out the school's basement. Fridge discovers an old video game console with a game called Jumanji, and the kids set it up, pick characters and begin to play.
They're immediately sucked into the game's jungle setting — and into the bodies of their avatars. Spencer becomes Dr. Smolder Bravestone (Dwayne Johnson), Fridge turns into Moose Finbar (Kevin Hart), Martha is Ruby Roundhouse (Karen Gillan) and gorgeous Bethany is horrified to find she's an overweight middle-aged man named Professor Shelly Oberon (Jack Black). They discover what their special skills are in order to survive the game.
