Ten years after college, our Pitch Perfect hero Bumper Allen lives a boring existence working as a security guard for his alma mater and singing a capella as a hobby with the less-than-eager Tonehangers. But after a surprise phone call from an old acquaintance, Pieter, Bumper is convinced he can make his musical dreams of becoming a pop star come true by dropping everything and moving to Berlin. With the help of an entourage of German collaborators, Bumper's goal is to perform a hit single at the famous German Unity Day. Bumper grows as both an artist and a person, finally learning what it means to work hard, and finds long-lost confidence and romance along the way.
