Known to many as breakdancing, breaking sprung up in the economic and social unrest of 1970s New York, as a form of expressive protest. Today, it is also a globalised and dizzyingly virtuosic competitive dance sport - and now it is making its debut at the Paris Olympics. We follow Australian competitor Rachael Gunn (B-girl Raygun) as she hits pause on her day-job as a university lecturer and prepares for her debut on the Olympics stage. In conversations across the final 100 days, as she practises at home in Sydney, tests out new moves in the UK, and gets settled in Paris, we hear about the challenges of training, experimenting, and honing her performance.
