Hellfire

On the Syria-Iraq border, a British hostage is beheaded by IS terrorists. The executioner is a young British extremist. A masked figure watches him - they call him the Caliph.

In Nigeria, the British High Commissioner and his young aide are kidnapped. A four-person SAS team, including hero Danny Black, is deployed to find him, and on arrival they find utter devastation. Prisoners infected with a mysterious plague reveal a plot to unleash a bio-terror attack upon the world - and against a ticking clock, Black and his team must stop the terrorists and identify the Caliph before deadly disease breaks out . . .
