Initial ideas, plots, characters etc for my own film opening.

So far i have found it difficult to come up with ideas for my own film opening, however after brainstorming i do have a few ideas which i may or may not use when it comes to the final filming. The plot i propose is going to be quite rural, in the countryside with not many people about. I would start the film off in by filming a car driving along a road from a distance and then finally going in to the car to hear the passengers speaking. There would be four males in the car, or two males and two females, i am yet to decide, and also what they will be talking about is still undecided. where they would go while driving would be an abandoned house or barn, and then i would end the opening on them opening the door to the house, leaving it on a cliff hanger.
