Pauline Hargraves (Evalyn Knapp) is the intrepid daughter of Professor Hargraves (James Durkin), a noted doctor of chemistry and archeology. She and Willie Dodge (Sonny Ray), her father's cowardly secretary, have accompanied Prof. Hargraves to Asia in search of a legendary ivory disk which may contain the chemical recipe for a deadly gas created by an ancient Egyptian named Confu. Unfortunately, the villainous Asian warlord, Dr. Bashan (John Davidson), is also after the disk, along with his right-hand-man and assassin, Fang (Frank Lackteen).
