The Bellas take on the world in a new television promo for Pitch Perfect 2, Digital Spy reports.

Anna Kendrick, Rebel Wilson and Anna Camp are all back along with new addition Hailee Steinfeld to conquer the most prestigious a capella singing competition in the world.

The disgraced Bellas have one shot at regaining their past glory, but only if they can triumph over the best a capella groups from across the globe.

Pitch Perfect 2 reunites much of the cast from the original movie, including Adam DeVine, Skylar Astin, Hana Mae Lee and Elizabeth Banks.

Banks is also producing and directing the sequel, with the first film's screenwriter Kay Cannon on board as well.

The Pitch Perfect characters are loosely adapted from Mickey Rapkin's non-fiction novel of the same name.

Universal Pictures will release Pitch Perfect 2 on May 15 in the US and the UK.
