An 1938 Italian historical war film that portrays the life and death of Pietro Micca who was killed in 1706 at the Siege of Turin while fighting for the Duchy of Savoy against France in the War of the Spanish Succession.

The Turin noblewoman Maria Clotilde di Bard, the sole and elderly heir to an ancient Savoyard title, is reduced to living in the attics of the palace due to the embezzlement of a dishonest administrator. The young lady, who has always been alone due to a great love that never led to marriage with Baron Nigra, befriends the daughter of the palace owner, who tells her about her love for an aeronautical engineer: an unhappy love, because her father is against it. Maria Clotilde discovers that the young man is her brother's illegitimate son, taken away at an early age and never recognized, and therefore the sole heir to the Bard name. The shady administrator also ruins the new owners, who find themselves penniless. But in a trunk kept by the damsel there is years of correspondence between her and Baron Nigra, whose immense historical value restores the Bard family to its former glory and thus allows for a happy ending with the marriage of the two young people.

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.
