Dorothy Segda plays three roles in this film which begins with the birth of twin girls to a Budapest mother (Dorothy Segda) in 1880. Orphaned early on, the girls are forced to sell matches on the streets until both are adopted by two separate families. Flash forward to 1900: Having lost track of one another, the grown-up twins take separate compartments on the Orient Express. One of the girls (Segda again) has become the pampered mistress of a wealthy man; the other (Segda yet again) is a bomb-wielding anarchist.
