Demonstone on AllMovie

In this politically-charged supernatural action-thriller from the Philippines, a beautiful television correspondent finds herself possessed by a vengeful demon, a former Chinese mystic who was slain by a Filipino warlord 500 years before. Before the mystic died he swore he would slowly destroy all of his descendants. The mystic makes good on his promise and the victims are killed ritually and branded with the mark of the dreaded demonstone to prove the revenge. The reincarnation of the warlord, now a corrupt Filipino politician, tries to find the killer, but has no luck until an American Marine, Tony McKee is found near one of the most recent victims. The politician immediately frames him for the death. But fortunately, former Marine Andrew Buck is there to prove his innocence. Unfortunately, Buck's girl friend is the demonically-charged reporter.
