In medieval France in 1349, the plague not only ravaged entire cities, but the Hundred Years War and the Inquisition also raged in the country. Here, we undertake a journey through the darkest days of the plague with two siblings, Amicia and Hugo. They are thrown into a merciless and cold world. A cruel and brutal Inquisition seems to be the only means against the plague, but the country is still overrun by a gigantic horde of rats. They are the embodiment of everything the plague stands for: death, disease and horror.
