Yasmiri, the daughter of a chieftain of Persian hillsmen, falls in love with Tommy Farrell, an English officer stationed at the Khyber Pass. Yasmiri's family deplores her infatuation and seeks revenge against the British when Tommy dishonors her. They capture Irene, the governor's daughter whom Tommy loves, and plan to sacrifice her. "The White Panther," Bruce Wainright--actually another British officer and champion of victims of the desert bandits--rescues Irene and holds the angry natives at bay until the cavalry arrives. Tommy meets his death in a feud, and Irene and Wainright marry.—AFI
