A young man and a woman come to know each other while being treated in a dentist's. They are put under anesthesia and in the unconsciousness they fall in a love triangle with the dentist like in a dream. In the extremity of happiness and misfortune, they experience the transcendence of time and space and fulfill their lust. As a result, the affair is completely ruined. Wailing in great regret, they at last come to consciousness and reality.
