At night in the waterside towns of Jiangnan, a ghost lantern would always appear along the riverbank, drawing passersby near, never to be seen again.

Yet the truth beneath the ghost lantern involved more than the peace of restless spirits. It also revealed a secret buried deep within his family. When he pulled back the final veil, a fateful confrontation awaited him.
