In ancient legends, it is said that on stormy nights, one sometimes hears a strange whistling, followed by the appearance of huge black dogs. But these are not ordinary creatures; they are demonic beings unleashed by the wild hunt for lost souls. Rarely does one see more than one of them at the same time, but if all seven should come together, it signifies the end of the world. In the picturesque town of Kingsbury in the heart of Vermont, Rose Kerrigan mourns the death of her grandfather, a kind but peculiar old man. Soon, she will learn of the legend of the seven whistlers, for the ghostly dogs have come to Kingsbury in search of a soul that has been hidden from them. At first, there is only one, but each day more appear. And if they do not find what they are looking for soon, all of them may gather in Kingsbury.
