Princess Zeila, daughter of Caliph Oman III, is preparing to review the nobles who aspire to her hand. The sinister Prince Jafar plots in the shadows: the young musician Amin will see to it that love can triumph, with the help of the Genie of the Lamp.

Based on fact, Passaporto Rosso (Red Passport) details the plight of a group of poor Italian immigrants who are hired as railroad workers in turn-of-the-century South America. In addition to facing poverty, deprivation, and prejudice, the immigrants are also bedeviled by a raging fever epidemic. Finally achieving a measure of prosperity, the Italians are forced to confront tragedy once more when their grown children march off to WWI. Though Isa Miranda is top-billed, she has very little to do in comparison with male lead Filippo Scelso. Passaporto Rosso was released in the U.S. as Destiny Unknown.
