Who is she? Prostitute or sophisticated adventurer, does she really love her, or is she a charming beauty who just wants to earn money? The relationship of these characters, reminiscent of a psychological duel, reflects their mutual attraction and distrust for each other, their loneliness and the desire to overcome it, the desire and fear of love.
