Personal idea for film

In my group we all came up with our own storyboard of what we thought would be a good idea for a film opening. I planned to have the story of a man who runs over a little girl. He returns home thinking he can get away with it but then he is not alone. The little girls spirit that he ran over is in his house. The girl stalks him until it drives the man to suicide. This idea was used in the final idea and storyline.
