What is it like to be young and find out you have got cancer? What you will find out in this film may surprise you. 　　This film, narrated by actor and comedian Jack Whitehall, tells 11 inspirational stories, revealing how a range of young people have dealt with their cancer diagnosis and the treatment process. We hear, primarily in their own words, about their fears, their hopes and their experiences - affirming the view that 'the best therapist for a teenager with cancer... is another teenager with cancer.' 　　Chloe, Harry, Liam, Tim and Matt introduce us to the bespoke ward facilities, specialist nursing and social worker support which is tailored to this age group - and which is largely funded by charities, such as CLIC Sargent, Macmillan Cancer Support and the Teenage Cancer Trust. Magda and Sophie give us an insight into the world of drugs development which is giving great benefit to some people - but Chloe's story tragically presents the argument that the age restrictions on drugs trials should be broadened. Nick, Yazz and Roisin reveal the depth and innovative nature of the support that goes into teenage and young adult cancer care. 　　What all their stories share is a sense of hope - and teenage bloody-mindedness.

Hannah Fry, a professor of maths, 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 overmedicalising 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.

The BBC's Horizon programme began in 1964, and since then has produced films looking at computer technology and the emergence of 'artificial intelligence'. 　　Our dreams always begin with ideology and optimism, only for this optimism to be replaced with suspicion that AI machines will take over. However, as the Horizon archive shows, throughout each decade once we have learnt to live with the new emerging technology of the time, the pattern begins again. We become once more optimistic, before becoming fearful of it. The dream for decades had been for a computer with AI to be embedded within a humanoid robot, but just as scientists began to perfect machines with these qualities, something happened nobody expected. 　　Today, AI systems power our daily lives through smart technology. We are currently experiencing a level of fear about the power of AI, but will we enter the next decade optimistic about all that AI can deliver - or fearful of its ability to control vast areas of our lives?

Horizon plunges down the biggest rabbit-hole in history in search of the smallest thing in the Universe. 　　It is a journey where things don't just become smaller but also a whole lot weirder. Scientists hope to catch a glimpse of miniature black holes, multiple dimensions and even parallel Universes. As they start to explore this wonderland, where nothing is quite what it seems, they may have to rewrite the fundamental laws of time and space.
