An advertising copywriter living a quiet, detached life in Tokyo becomes entangled in a strange and dangerous search after using a photograph in an ad that draws the attention of a powerful and shadowy figure. The image features a peculiar sheep marked with a star on its back, and he is given an ultimatum: find the sheep or lose everything. The photograph was sent to him by his old friend known as “the Rat,” who has since disappeared without explanation.

As he follows the trail north to the remote landscapes of Hokkaido, accompanied by a woman with unusual abilities, the search takes on a deeper and more unsettling significance. Clues left behind by the Rat suggest that he may be connected to the mysterious sheep—and to a force that exerts influence over those it inhabits. What begins as a coerced investigation gradually becomes a personal journey tied to memory, absence, and the lingering weight of past connections.

Blending mystery with surrealism, A Wild Sheep Chase explores themes of identity, control, and emptiness. At its heart is the narrator’s search not only for the sheep, but for the meaning of his relationship with the Rat—and the quiet, unspoken forces that shape their lives.
