Ella is a true sex maniac. Thanks to her position as an accountant in one the the big companies in the London "City", she manages to show herself as a strict, rigid and flawless woman. Between her charts and sales figures, her private and business lives follow a very strict pattern. But two nights per week, her sexual impulse takes over and reveals a whole different character. Not being able to restrain her desires, Ella turns into a huntress. Pubs, private clubs or even a simple public park, her hunting territory is limitless. Her preys, men and women from all classes, alone or in groups only serve her needs, without any feelings. Once she's done with them, Ella goes back to her regular life... until next time.
