Richard Silva's hell on earth begins in the fall of 1970 when his plane is shot down over North Vietnam. The decorated US Air Force lieutenant is captured and taken to a POW camp. Only a supreme effort of will keeps him from breaking down.
But his ordeal was just beginning. Richard Silva is turned over to a shadowy interrogator -- known as the Imp -- who specializes in the systematic torture of American prisoners. Miraculously, Silva survives and returns to the US.
He finds an America that is profoundly different from the country he left, but America isn't the only thing that has changed. Silva's mind has been horribly altered. For him there is only one way out: Find the man who stripped him of his humanity. Find him and kill him.
