Representatives of the male, intoxicated with a thirst for possession, leave with a young and sexy girl, hoping to have a good time and have an unforgettable night with a beautiful woman. Having brought their companions to a cheap hotel, or their own apartment, or a car parked nearby, the girl starts showing off her charms to her partners, stirring them even more. Disturbed by passion, men stop thinking, and it is at this point the girl is getting from them what she needs - their warm and hot blood. The girl is a vampire who has lived for many years.
