In a remote mountain village of 15th-century Joseon, a humble headman, Heung Do, hears a rumor that any village hosting an exiled nobleman will be blessed with abundance and fortune. Hoping to bring prosperity to his impoverished community, he eagerly submits a petition to host one—unaware that his guest is none other than the fallen monarch, the deposed boy, King Danjong. While an unlikely bond begins to form between the dethroned ruler and the man assigned to watch over him, the quiet village finds itself drawn into the perilous undercurrents of royal intrigue—where loyalty and survival collide.
