De overleden ziel Su-hong en zijn drie levensechte beschermers zien de resterende beproevingen onder ogen om hun reïncarnatie te verkrijgen. Ondertussen komen de bewakers oog in oog met de begraven waarheid van hun tragische tijd op aarde. Dit culmineert tot een intens gevecht met een kwaadaardige god.
