Your Ticket is No Longer Valid (1981)

Sexual obsession provides the basis of this taut thriller, an adaptation of a Romain Gary novel. The story centers upon a prominent financier who must fight to save his crumbling business empire and his rapidly fading manhood. The obsession begins when the impotent magnate begins dreaming that a handsome gypsy is making love to his much younger girlfriend. He cannot get the dream out of his head and so goes to a Parisian madam to see if he can make the fantasy real. ~ Sandra Brennan, Rovi
