A mysterious and deadly disease breaks out in a remote town built upon old tanneries and butcheries. Whilst the disease can be identified by physical symptoms, its roots and origins remain mysterious. The disease is highly infectious and deadly. It affects the neural and the blood-circulating systems, crippling both body and mind.
To fight the epidemic the local authorities first send a learned doctor, then an inquisitor ordered to assess the situation, then a military commander. The first has to investigate the disease and find an optimal solution; the second has to save as many lives as possible while executing said solution; the third has the right to exterminate the whole Town should the others run out of options.
Along with the authorities’ agents two volunteers find their way through the Town along with the learned doctor, who goes by the name of The Bachelor. One of them, The Changeling, is a strange girl who believes she can heal with her hands, and the other, The Haruspex, is a talented amateur who’s fond of experimental surgery.
