Pitch Perfect: Riff Off (Sing Off) Scene
In this official clip for "Pitch Perfect" the cast signs a mashup of Rihanna's "S&M", Foreigner, Salt 'n Pepa's "Let's Talk About Sex" and Blackstreet's "No Diggity". Beca, a freshman at Barden University, is cajoled into joining The Bellas, her school's all-girls singing group. Injecting some much needed energy into their repertoire, The Bellas take on their male rivals in a campus competition.
A comedy set in the middle of a war between rival a cappella groups and centered on a rebellious girl who joins one of the groups as an escape from her unhappy life at school.
