Agent Michael Ryans sets out on an investigation with an agent in training, Melissa Change. Together, the pair will have to undergo hours of interrogation with one of the world's most dangerous people, gas attack bomber and former Nazi, Harold Regenold. They do this in order to receive subtle hints about the identity of a person committing similar crimes as Regenold did in his reign. They suffer a brutal and fearful task to find just one smudge of information, but will they get what they want, or will they get what they need?
