Le Vertige.

The film opens with the overthrow of the Czar during the 1917 Russian revolution. The family of General Count Svirsky (Roger Karl) cower in their home, certain that the mobs of angry peasants will tear them apart. But even in this moment of crisis, Svirsky can find time to murder the young officer who has been having an affair with Countess Svirska (Emmy Lynn). The Countess knows what has happened, but she loyally remains with her husband as they escape to the safety of the French Riviera. It is here that the Countess meets Henri de Cassel (Jaque Catelain), the “living image” of her dead lover.
