A nine-tailed fox named Lee Yeon walks among humans in the city, wielding supernatural power to purify corrupted minds while leaving destruction in his wake. When Ji Ah, a fearless broadcaster hungry for her next viral story, catches wind of his existence, she becomes obsessed with exposing him on her show about urban legends. What she doesn't anticipate is how dangerously attractive and intelligent he is, or how willingly he steps into her spotlight. Beneath this tense dynamic lurks a darker threat: Lee Yeon's half-brother Lee Rang, another gumiho far more sinister in nature. Half-human yet consumed by hatred for humanity itself, Lee Rang represents the violent potential Lee Yeon keeps controlled. As Ji Ah investigates deeper, she finds herself caught between two supernatural beings with conflicting natures, unable to distinguish predator from protector. The line between exposure and entrapment blurs fast, and her hunger for truth may cost her everything.
