Seventeen-year-old Asha is a rebel, inspired by historical revolutionaries and unafraid of pointing out the hypocrisy around her – but less sure how to actually dismantle it. Her younger sister, Bettina, wide-eyed and naive, is just trying to get through the school day without having her pocket money nicked.

With essays to write, homework to do, and bus journeys home, the two sisters meet every afternoon, outside the school gates, to tackle the injustice of the world.

Sonali Bhattacharyya's play Two Billion Beats is an insightful, heartfelt coming-of-age story and a blazing account of inner-city, British-Asian teenage life.
