The Barden Bellas, after conquering the world of a cappella music, find themselves at a point in their lives where the transition to adulthood isn't so easy. After graduating, each has taken different paths: some are struggling with boring jobs, while others are trying to keep their musical passions alive. But life takes a new turn, and our girls decide to reunite for one last hurrah: a tour across Europe.
However, this isn't just any trip. The Bellas face a new challenge as they compete against professional bands that play with instruments and are truly talented. To make matters worse, they must deal with the pressure of adulthood and the relationship issues that have arisen since they parted ways. As if that weren't enough, tensions between old and new friends threaten to boil over.
With the help of a couple of old allies and a bit of a cappella magic, the Bellas seek to prove that friendship and a passion for music are more important than any trophy. In a burst of hilarity, emotion, and a ton of catchy music, our heroines weigh what it truly means to be part of a group and how to find their place in the world. As they realize, no matter how far they go, they will always carry with them the sisterhood they created together.
