        Trobakoff, who has opened a cabaret there.
        Her car is ready, the 
        motor running. Vicky is behind the wheel while the Queen, lost in a wave 
        of nostalgia, hums the refrain from Lieutenant Were You Once With The 
        Hussars? 
        
        They've already driven quite a while when 
        suddenly another car appears on the road ahead of them.
        
        Vicky's pride makes him 
        try to overtake it; but this has dire consequences as they collide.
        A not unpleasant looking 
        man climbs out of the other car and immediately tends to the Queen who's 
        still in a state of shock. During all this, Vicky tries to make 
        necessary repairs to his car.
        
        A heated discussion 
        ensues. Suddenly there's a thunder storm and it begins to rain in 
        droves. Thus, the handsome stranger offers to drive the Queen, in his undamaged vehicle,

        Alexandra gets increasingly tipsy and 
        begins, as she was accustomed to do when she was queen, 
        to speak to her table partner in a tone of voice that is decidedly 
        dominating and military.
        The stranger supposes 
        that she is an actress and asks where she has appeared on stage.

        Alexandra 
        Alexandra is desperate to remain incognito and 
        hastily searches through an old musical score closet to find  some 
        hits that she can sing. She finally stumbles upon something which, 
        despite her stage freight, she performs, eliciting great applause from 
        the audience, but especially from  « Romeo » who is particularly 
        enthusiastic. He invites Alexandra for dinner. Then, there in a loge at 
        the Red Lantern, the couple exchanges their first kiss.

        stranger's car.
        Everything 
        Everything suggests that he's none other than the
        leader of the revolution, the ruthless Fedor Karew who, with the help of 
        this important document of State, intends to raise money for the new 
        republic.
        Alexandra is shattered. She wants to immediately break up with him. In 
        the mean while Fedor has noted the document's disappearance.
        He suspects 
        that Alexandra is involved, asks her to return it and accuses her of 
        being a spy.
« The future of an 
        entire country depends on this document  » he says. So it is 
        returned to him. But once he has left, Alexander breaks down in tears. A 
        new lease on life had winked at her and the disappointment was 
        horrible... 
        
        Revolutions are followed by counter revolutions. In Gregorien the 
        monarchist party grows stronger again. Alexandra is called back to 
        retake her throne. She answers the regime's call, but only so that she 
        can protect her still beloved conspirator.

        There's nothing left that Alexandra can do. 
        Despite all their efforts, the money that Fedor raised in Paris has come

        all his ambitious plans. Instead of politics, he only wants to live 
        happily with Alexandra.
