Ronan receives a mysterious gift from his brother, Roy: a severely injured red fox. He tenderly cares for it, which surprisingly transforms into a human once healed. This human, named "Eugene White," reveals he is a fox spirit training for ascension but was subjected by his master to three earthly trials—resentment, separation, and unfulfilled desires—to achieve celestial transcendence. What Ronan doesn't realize is that he is not just Eugene’s caretaker but also his destined trial.
