Okay, I know it starts w/ a guy getting caught taking a photograph of a murder scene I believe. And throughout the whole movie he's talking to his best friend who is a woman. They try to figure who the murderer is. I think or I'm not sure the murderer kidnaps the friend. So he goes to this shack or something that has stairs that lead under the ground to look for her. He hears whispering and someone talking behind a door that's cracked open a little. He goes in w/ a gun and starts confronting the murderer and he finally is able to shoot him in his stomach I believe. When the cops get there they only find him w/ a gunshot wound and mumbling about his friend and the murderer. But then it turns out he was the murderer all along and his friend was just a figment of his mind.
