An aging New Yorker, a writer named Nick, feels life ebbing out of him. The world has gone to hell and Nick is so sick of it all that he can't even have a glass of champagne. Then one night he meets a tantalizing young woman who agrees to come back to his apartment. Their encounter is the most strangely extraordinary of his life. Propelled by uncontrollable, primordial desires, he enters a new and unimagined dimension of the forbidden and is filled with a sexual and spiritual ecstasy that is as intense as it is unholy. Suddenly Nick's senses are alive. He feels strong, unconquerable, beyond all inhibition and earthly morality. He indulges in life's pleasures, pure and perverse, sublime and dangerous, from the delicate flavors of the perfect tomato to the fleshy beauty of a woman's thigh. But Nick's desire to sustain his rapture leads him to a madness and a darkness far greater and dreadful than have ever ridden the demon mares of night.
