Here is an opening that might work better with reasons why.
Granted your movie is probably not horror / supernatural, but you can apply the same principles no matter what the genre.
FADE TO BLACK:
Maddy V.O.
How long has it been?
EXT. ROADSIDE DITCH - NIGHT
MADDY, 21 dressed in conservative clothes, looking like the girl you would take home to mother, rolls down into the bottom of a ditch. She is beaten, torn, bloody. At first glance the way her clothes are ripped and torn you would think someone had raped her or attempted to rape her.
In her hand is clutched a wolf's head ring.
Several people appear behind her wearing Egyptian masks and long capes.
One reaches down, pries the ring from her fingers, holds it up high to show it to everyone.
A bright rainbow of lights emanate from the ring.
EXT. MADDY's HOUSE - MORNING
Why:
FADE TO BLACK: covers the gauche V.O. prior to FADE IN:
I put her in conservative clothing so the audience immediately knows something about her and so when the audience believes she was raped they will feel more sympathy for her. A girl dressed as a hooker will not get as much sympathy: someone will say, "She asked for it."
I put in the potential rape so that the rest, which is trite in and of itself, will have more effect and to set the audience up for the belief, "You better watch this movie close because what you first expect is not necessarily what is going to happen.
The wolf's head ring sets the audience up for, but does not anticipate the Egyptian masks: Thus even though they are not expecting Egyptian masks they don't come "out of the blue" and the audience does not feel cheated. A sort of "unexpected but inevitable" applied in the first scene.
The Egyptian masks and the emanations from the ring tell the audience what kind of movie they are watching.
Now the audience is prepared to wonder, "How did a nice girl like her get in a place like this?"
Is this too cold blooded and analytical? When writing a novel the answer might be yes, but when writing a screenplay the answer is that no amount of analysis can be too much: Every detail has to count at least once, and if possible three times.
