Beca (Anna Kendrick), freshman at Barden University, has never been one to follow the pack, always marching to the beat of her own rebellious drum. Struggling to fit in with any one group, she winds up joining The Bellas, an all-girls singing group in her school. The only thing any of these girls have in common is how good they sound when they sing together.
Beca takes it upon herself to revamp the group's sound, giving them the edge they need to take on their rival boys group in a head-to-head campus competition.
Based on the book Pitch Perfect: The Quest for Collegiate A Cappella Glory written by Mickey Rapkin.
