The Ebola virus. No-one knows exactly where it comes from but one thing is certain - it's one of the most virulent infections known to science.

Reveals just how dangerous too much fat is to our most vital internal organs. The programme follows a specialist pathology team as they conduct a post-mortem on the body of a 17-stone woman whose body was donated to medical science.

Morbid obesity reduces life expectancy by an average of nine years and is blamed for over 30,000 deaths in the UK every year. With 65 per cent of people already overweight or obese, this extraordinary film is a powerful contribution to the debate about fat, food, lifestyle and how the health service will cope with the growing obesity crisis.
