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.
