A bloodstained man runs half naked down a motorway at night. Cornered by police, admitted to a psychiatric ward suffering from trauma-induced amnesia, all he can recall is a detailed knowledge of sophisticated weaponry.
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, it is to Brecon he drags Elizabeth Santer with the security forces in all-out pursuit. Is Elizabeth in the hands of a homicidal terrorist or an innocent pawn?
