A bloodstained man runs half naked down a motorway at night dodging high-speed traffic - and worse. Cornered by police, admitted to a psychiatric ward suffering from trauma-induced amnesia, all he can recall is a detailed knowledge of sophisticated weaponry and military techniques that indicates a background in terrorism.

When two armed soldiers guarding his room are murdered and Dr Elizabeth Santer, the psychiatrist assigned to his case, is abducted at gunpoint a desperate hunt begins for a dangerous killer.

Terrorist - murderer - kidnapper - thief whatever he is, he remembers a town in Wales and it is to Brecon he drags Elizabeth Santer with the security forces in all-out pursuit. There, a violent and bloody confrontation exposes a horrifying story of treachery and political cover-up.

Is Elizabeth in the hands of a homicidal terrorist or an innocent pawn? Her life depends on the right answer.
