In an enthralling documentary, Dan Snow and archaeologist Raksha Dave delve into the catastrophic impact of the Black Death on Britain 700 years ago, a pandemic that extinguished around half of the population, or three million people. The duo embarks on a journey to trace the origins and merciless spread of the plague, starting from its arrival on Britain's South coast in June 1348, through the bustling trade routes that brought the disease to Melcombe Regis, Dorset. Their investigation takes them to various hotspots of the outbreak, including the Old Operating Theatre in London and Wildwood Animal Sanctuary in Kent, where they explore the role of rats in dispersing the bubonic plague. Through dramatic reconstructions and visits to places like Nottingham University's biomedical laboratories, they uncover the rapid spread and deadly impact of the plague, offering a month-by-month account of how it ravaged the country, decimating cities, towns, and villages alike.
The documentary not only showcases the horrific symptoms and desperate attempts at cures through brutal medical practices of the time but also leverages cutting-edge research to explain why the Black Death remains the deadliest pandemic in history. The personal stories of victims, from princes to paupers, are brought to light, revealing the indiscriminate nature of the disease. Dan's visit to Canterbury Cathedral and Raksha's investigation into the recent discovery of mass graves beneath a tranquil London square underline the widespread desperation and devastation. Their journey through the history of the Black Death, culminating in the discovery of its indiscriminate toll and the unveiling of mass graves in London, not only sheds light on the darkest chapters of British history but also ignites a profound understanding of the tragedy, making a compelling case for why this documentary is a must-watch for anyone interested in the profound impacts of pandemics on human society.

The documentary, an own production, immerses the viewer in a journey that blends science and philosophy, questioning the nature of time and unveiling a 4-dimensional universe, where space and time are integrated. We are invited to consider a universe in which past, present, and future coexist, suggesting that our linear perception of time might be more of a mental construction than a physical reality. The narrative progresses by exploring how quantum particles exist in states of probability until they are observed, at which point they acquire defined properties. Then, the provocative hypothesis is presented that observation also fixes the temporal dimension of the particles.
The sensation of the flow of time and the distinction between past, present, and future are introduced as mental constructions, arising from the human brain's limited capacity to process the complexity of reality. It is then proposed that the mind, by observing itself, fixes itself in the temporal dimension, thus creating the illusion of the present. Finally, the impact of these theories on free will is discussed.
This documentary challenges viewers to look beyond their everyday perceptions and consider the possibility that reality is much more complex and fascinating than our immediate experiences suggest. It is an invitation to explore the limits of science, philosophy, and the mind itself in search of answers to some of the deepest questions of existence.
