An idea from my sick mind which could either turn out seriously disturbed or very campy.
My protagonist takes the cab of a driver who makes it an occasional practice to drive drunken girls to a deserted spot, rape them and drive off. He's never been caught, never looked back. One night, she finds herself at the mercy of this rapist cabbie but somehow, some form of Stockholm syndrome takes place and she ends up inviting him over to her place for more of the same.
This evolves into a seriously twisted relationship... (more input would be welcome!)
Looking for a male player with either very sadistic tendencies or dark humour!
