The American Construction Syndicate wants to build a railroad across Baluchistan, as part of their plans for global development. The company appoints a commission, headed by Colonel Piedmont Moore, to obtain the right of way from the Baluchi ruler. Moore chooses his personal friend and physician Dr. Warner as his second in command; and with commendable nepotism he selects his son Allison Moore as the commission's surveyor. Dr. Warner's ebullient daughter Bessie wants to come along, and solicits Moore's daughter Janet to come too; the young women will by chaperoned by Bessie's Aunt Lucy. (Col. Moore is secretly pleased that his daughter Janet will make the trip; she has been melancholy after an unhappy love affair, with a man the Colonel regards as a thief and scoundrel.)The Americans travel to Baluchistan, and promptly get themselves imbroiled in a succession conflict. The reigning Khan of the country is dying, and two cousins vie for the crown. One, Kasam, is masquerading as their guide. What follows is a complex but tightly-woven plot that involves subterfuge and conspiracy, poisonings and attempted assassinations, sword fights and a pursuit in the desert, a scheming femme fatale, disguises and false identities - all the ingredients of melodrama.In the end, Prince Kasam's rival Ahmed (or Hafiz) inherits the throne of Baluchistan - but he yields it to Kasam so he can return to the United States with the heroine, Janet Moore. It is revealed that Ahmed/Hafiz is actually Howard Osborne, the man Janet had previously loved (and secretly married, seven years before). Osborne had nobly but foolishly taken the blame for an embezzlement actually committed by Allison Moore, the Colonel's son and Janet's brother. Once all the secrets are out, the difficulties are resolved; and the requisite happy ending is achieved. And Bessie stays behind to marry Prince Kasam, and become the Khanum of Baluchistan.
