Idea for thriller

The Idea I had for my Thriller would be a girl being followed, stalked and hassled by a masked stranger, in my opening sequence we would see her waking up receiving a text from an unknown number she would tut under her breath as if she thinks it is a prank, this would need a zoom, then we would see shots of her eating breakfast. Then we would see her walking into the bathroom to see writing on the mirror here there would be a shot reverse shot of her reaction, and then she starts to run. all throughout the house shots the camera would be following her as if someone is watching, then when she is running to school we would see her captured, and brought back to her kidnappers house, this would need fast pace, tracking shots and the mise en scene would include her clothes being ripped, hair pulled and the stalker would be in black with a mask, when she is in the kidnappers house she would be tied to a chair before the ‘masked stranger’ removes his mask, here we would see shot reverse shot and close ups of her reactions, before she realises that the kidnapper is her uncle, he would say “my long lost niece” then she is gagged and knocked out. The screen would go black.
