By the close of the Industrial Revolution, the American food supply was tainted with frauds, fakes and legions of new and untested chemicals, dangerously threatening the health of consumers. Based on the book by Deborah Blum, The Poison Squad tells the story of government chemist Dr. Harvey Wiley who, determined to banish these dangerous substances from dinner tables, took on the powerful food manufacturers and their allies. Wiley embarked upon a series of bold and controversial trials on 12 human subjects who would become known as the “Poison Squad.” Following Wiley’s unusual experiments and tireless advocacy, the film charts the path of the forgotten man who laid the groundwork for U.S. consumer protection laws, and ultimately the creation of the FDA.

Xand van Tulleken, Raksha Dave and John Sergeant discover the parallels of the Great Plague of 1665 with the Covid-19 pandemic. Ch1. Outbreak The epidemic is traced back to its source in the parish of St Giles in the Fields, now at the heart of London's theatre district. The program also examines the symptoms of the disease and uncovers new research into the plague bacteria that could overthrow accepted ideas about how the infection was spread. Ch2. Decimation Xand heads to St Barts hospital to look back at historical records which show that nursing staff stayed behind and risked their lives to help the sick. Elsewhere, John investigates why infection rates were so different between the rich and poor, examining clothes typical for each group in the 17th century. Ch3. Aftermath Xand visits Samuel Pepys' parish church and discovers the sad tale of the Poole family, who within 11 days lost all five of their children. He also heads to Eyam in Derbyshire, revealing the heroic story of self-sacrifice that saw all 700 villagers lock themselves in to try to stop the disease from spreading to surrounding areas. Raksha Dave trials 17th-century disinfection methods and reveal a surprising substitute that can be just as effective as modern antibacterial cleaners.

Psychopaths have long captured the public imagination. Painted as charismatic, violent predators lacking in all empathy, they provide intrigue and horror in equal measure. But what precisely is a psychopath? What is it that drives them to cause harm, even kill? And can they ever be cured? Presented by psychologist professor Uta Frith, this is an in-depth exploration of the psychopathic mind including one of the most notorious of all, Moors murderer Ian Brady. Through an ongoing correspondence between the Horizon team and Brady, the film features some of the very last letters he wrote. The film also features a series of candid interviews with prison inmates who not only describe their crimes but why they think they committed them. Horizon explores not only how each individual's crimes were shaped by their own life experiences, but also gives an insight into how these people think and behave. Working with the world's experts in the field, the film sheds light on the biological, psychological and environmental influences that shape a psychopath. And it looks to the future, with groundbreaking research that suggests a lifetime of incarceration is not the only option to manage violent and dangerous psychopaths.
