The government rates the global outbreak of a deadly flu virus as a major threat to the UK. It could happen at any time. To predict the impact of the next pandemic more accurately than ever before, new data is needed. Dr Hannah Fry is on the case. She sets out to recruit the nation to download the BBC Pandemic app in a ground-breaking experiment to help plan for when that happens. How quickly will it spread? How many could it kill? What can we do about it? Hannah masterminds the experiment and adopts the role of Patient Zero by walking the streets to launch the outbreak. Meanwhile, an emergency physician finds out why flu is still such a danger a century after flu killed up to 100mi people. He meets researchers trying to discover what makes some people more contagious and visits a factory that will produce vaccine when the next pandemic flu virus emerges. Armed with the information he gathers and the results of the BBC Four Pandemic experiment, they make a shocking revelation.

Hannah Fry, a professor of math, is used to investigating the world around her through numbers. When she's diagnosed with cervical cancer at the age of 36, she starts to interrogate the way we diagnose and treat cancer by digging into the statistics to ask whether we are making the right choices in how we treat this disease. Are we sometimes too quick to screen and treat cancer? Do doctors always speak to us honestly about the subject? It may seem like a dangerous question to ask, but are we at risk of overmedicalizing cancer? At the same time, Hannah records her own cancer journey in raw and emotional personal footage, where the realities of life after a cancer diagnosis are laid bare.
