A man just broke up with his girlfriend who was a photography. Intimate portraits or material for a models portfolio is what she usually did. He saw some of those woman and he knew what the next chapter of his life would be. There is lots of technique and psychology used to get the object of the film or portrait to pose certain ways and those things he knew. He just wanted to get to know more about the technical aspects of filming and photographing subjects. He decides to take a class which is taught by a former model turned director. Not big films but 10 min horror films for festivals or some such.
She immediately takes a liking to her and discovers that she is bisexual. He says to her. "You have given me all the tools to make this a career. Do you mind if I do some nudes of you? You can judge them? She is impressed and decides to watch him direct a small porn film and she is so turned on that she is all over him when they watch it together. Each knows the kinky side of the other. They make a pact to write a screenplay for a full length horror film which they will shoot in on a remote island. She is already loaded with money to back the project. They agree he will pick out what men she desires and she will get him the woman.
Once on the island all sorts of things can happen. Maybe they decide that they are only accepting applicants with no close ties who won't notice them missing and proceed to keep them for themselves. Maybe the two main characters have a fight and one of them decides to get the aid of the others to torture, lock away, or even plan murder. Maybe as the murders take place in the flm it is not faked but instead they are taken away to be slaves or anything similar while the others wonder what is going on. Perhaps the hired help controls the two photographers. Please pm me if you are interested or have other ideas
