In an age-old war, that of Gyõz versus Garroul—vampire against werewolf—the Gyõz finally have the upper hand. Having built a crude but effective prison, the Gyõz are systematically rounding up the Garroul, and forcing them to work for them. When two men find themselves incarcerated in the vampire's labour camp, all they want is to get out, but, along with the other maltreated inmates, even their thoughts of escape are prevented by a high-pitched and head-splitting broadcast that keeps those with monthly-canine ears well and truly in the dog's house. It is a plan of genius, designed by the greatest vampire minds. But even the best laid plans can be plotted against.
