In Joseon's capital of Hanyang, rumors are spreading of an evil king cursing the kingdom with ghosts. First, there's the wailing man pulling an empty handcart.

To investigate, the prince calls his outcast brother, spirit seer Lord Muyoung, who comes down from the mountains with his skittish young disciple Haerang. Can this pair unravel the mystery, or will they too get caught in the web of royal curses and vengeful ghosts?
