Gina McKee stars in this chilling apocalyptic radio drama by award-winning writer Val McDermid. It's the summer solstice weekend, and 150,000 people have descended on a farm in the northeast of England for an open-air music festival. Reporting on the event is journalist Zoe Meadows, who files her copy from a food van run by her friends Sam and Lisa. When some of Sam's customers get sick, it looks like food poisoning, and it's exacerbated by the mud, rain and inadequate sanitary facilities. It's assumed to be a 24-hour thing until people get home and discover strange skin lesions, which ulcerate and turn septic. More people start getting ill - and dying. What looked like a minor bug is clearly much more serious: a mystery illness that's spreading fast and seems resistant to all antibiotics. Zoe teams up with Sam to track the outbreak to its source; meanwhile, can a cure be found before the disease becomes a pandemic? From a number one best-selling author, this original drama envisages a nightmare scenario that seems only too credible in our modern age.
