An unnamed UK metropolis. The future. Photojournalist Jennifer Preston is investigating the aftermath of a freak explosion known as 'the Catastrophe' that ripped through the city on New Year's Eve. A sprawling, militarized Quarantine Zone has been erected around the blast site; nobody goes in and nobody comes out.

As unexplained acts of violence erupt across the city, Jennifer begins to notice strange, ephemeral phantoms in her photographs and her investigation becomes a race against time. Can she discover the cause of the Catastrophe before the dangerous and powerful conspirators orchestrating events get to her and those closest to her?
