An introspective young boy, Joseph Coppock is trying to make sense of the world. Living alone in an old house, he spends his time reading comic books, collecting birds' eggs, and playing with marbles. When one day a rag-and-bone man called Treacle Walker appears on a horse and cart, offering a cure-all medicine, a mysterious friendship develops and the young boy is introduced to a world beyond his wildest imagination.

Luminous, evocative, and sparely told, Treacle Walker is a stunning fusion of myth, folklore, and the stories we tell ourselves.
