An accidental collision on a Bangkok sidewalk goes very wrong when the man who ran into Rafferty dies in his arms, but not before saying three cryptic words: 'Helen Eckersley. Cheyenne'. That night, Rafferty is interrogated by Thai secret agents who demand to know what the dead man said, but Rafferty 'can't remember'. When men in uniform then show up at his flat, he manages to escape and becomes a fugitive. It become clear that he's been caught on the margins of the war on terror and that his opponent is a virtuoso artist - whose medium is fear.
